This dual-energy X-ray absorptiometry (DEXA) scan report includes a whole-body skeletal image and a corresponding bone mineral density (BMD) graph. (a) The clinical image displays a full-body scan of a pediatric patient in the anterior-posterior view, with white geometric boundaries delineating standard regions of interest for density measurement, including the head, trunk, and extremities. The bones are visualized in grayscale, where varying intensities correspond to mineral content. (b) The lower panel presents a quantitative BMD graph for total body evaluation. The x-axis represents age (3–20 years) and the y-axis represents BMD (g/cm²). Color-coded percentile bands (green and blue) denote the age-matched reference range for a healthy population. A specific data point, marked by a crosshair at approximately age 11, sits significantly below the expected mean, correlating with a Z-score of -2.4. This diagnostic finding is characteristic of secondary osteoporosis, potentially related to chronic corticosteroid use or systemic conditions such as psoriasis. This educational material is suitable for understanding bone densitometry interpretation and pediatric metabolic bone disease.

This diagnostic image and data summary illustrate a Dual-energy X-ray Absorptiometry (DEXA) scan of the lumbar spine (L1-L4) used for bone mineral density (BMD) assessment. The visual component features a posterior-anterior (PA) view of the lumbar vertebrae, where each vertebral body (L1, L2, L3, L4) is segmented and delineated by rectangular regions of interest (ROI). Accompanying tables provide quantitative data including estimated area (cm²), Bone Mineral Content (BMC in grams), and BMD (g/cm²). The total BMD for L1-L4 is reported as 1.842 g/cm², with significantly elevated T-scores and Z-scores reaching +5.85. This clinical finding indicates abnormally high bone density, which is essential for diagnosing conditions like osteopetrosis or sclerosing bone dysplasias in endocrinology and orthopedics. The educational focus is on the interpretation of DEXA scan outputs and the recognition of supra-normal bone density values.

This diagnostic visual presents the results of a Dual-Energy X-ray Absorptiometry (DEXA) scan used for assessing bone mineral density (BMD) in the lumbar spine and femur. Section A depicts the Anteroposterior (AP) spine bone density for L1–L4, showing segmented vertebrae with corresponding BMD measurements (g/cm²), T-scores, and Z-scores in a tabular format. A reference graph plots the patient’s BMD against age-matched norms, using color-coded zones to categorize bone health (e.g., green for normal, yellow for osteopenia, and red for osteoporosis). Section B shows a similar analysis for the right proximal femur, highlighting the femoral neck, Ward’s triangle, and trochanter. Overlaid geometric regions on the femoral radiograph indicate the specific areas of interest for measurement. This content serves as a clinical assessment tool in endocrinology and orthopedics for diagnosing conditions like osteoporosis or monitoring treatment response in patients with metabolic bone disease.

This medical illustration depicts a Dual-Energy X-ray Absorptiometry (DEXA) scanner setup and its clinical applications. The central diagram shows a patient in the supine position on a scanning table. Key instrumental components are identified: an X-ray source positioned above the patient and a detector located directly beneath the table, illustrating the transmission of X-ray beams through the body. Textual annotations outline the dual utility of the modality: (i) Bone health assessment, which measures areal bone mineral density (g/cm²), and (ii) Body composition assessment, which quantifies fat mass (g) and bone-free lean mass (g). To the right, representative diagnostic images from a DEXA scan are displayed, including a skeletal view and a soft tissue body composition map. This visual serves as an educational summary of how DEXA scans utilize high- and low-energy X-ray beams to accurately differentiate and measure various body tissues for metabolic and musculoskeletal health evaluations.

This diagnostic image displays dual-energy X-ray absorptiometry (DEXA) scans used for Bone Mineral Density (BMD) assessment. The visual is divided into two clinical views: an anteroposterior (AP) view of the lumbar spine and a proximal femur scan. In the lumbar spine image, horizontal rectangular Regions of Interest (ROIs) are demarcated over the L2, L3, and L4 vertebrae to calculate specific density values. The right image shows the proximal hip, featuring geometric overlays that isolate the femoral neck, Ward's triangle, and the greater trochanter for analysis. These scans are critical in diagnosing metabolic bone diseases such as osteopenia, osteoporosis, or osteomalacia, which in this clinical context relates to drug-induced renal impairment and hypophosphatemia. The grayscale variations within the skeletal structures represent the relative mineral density, where higher-density cortical bone appears darker compared to more lucent trabecular areas.

A multi-panel figure illustrating a Dual-Energy X-ray Absorptiometry (DEXA) scan. Panel A displays a clinical X-ray of the lumbar spine (L1-L4) with segmented ROI (Region of Interest) boxes and vertebral outlines. Panel C shows an X-ray of the proximal femur, including the femoral neck and total hip, with standardized geometric boxes positioned for density measurement. Panels B and D provide the corresponding densitometry plots for the spine and hip, respectively. The graphs plot Bone Mineral Density (BMD in g/cm²) on the left y-axis against age in years on the x-axis, with Young Adult (YA) T-scores on the right y-axis. The plots feature a color-coded reference range: green (normal, T-score > -1), yellow (osteopenia, T-score -1 to -2.5), and red (osteoporosis, T-score < -2.5). In both graphs, a black square marker indicates the patient's data point, situated within the yellow/orange transition zone, signifying low bone mineral density and clinically significant osteopenia.

A pseudocolor Dual-Energy X-ray Absorptiometry (DEXA) scan of a proximal tibia in the anterior-posterior (AP) projection, demonstrating a periprosthetic bone mineral density (BMD) analysis after total knee arthroplasty. The image features three distinct Regions of Interest (ROIs) used to quantify bone remodeling around a tibial prosthesis. ROI 1 (medial) and ROI 2 (lateral) are 4 cm long rectangular boxes positioned immediately distal to the tibial component tray, spanning from the central axis to the respective cortical margins. ROI 3 is a 2 cm long rectangular area located immediately distal to ROI 1 and 2, spanning the full width of the tibial shaft. The color scale indicates BMD levels: yellow and orange represent higher bone density, while red and purple signify lower density. This visualization is used in orthopedic research to monitor stress shielding, bone resorption, or osseointegration adjacent to orthopedic implants over time.

Dual-energy X-ray absorptiometry (DEXA) scan report presenting bone mineral density (BMD) analysis of the lumbar spine and proximal femur. The image is divided into two clinical diagnostic panels. The left panel shows the lumbar spine (L1–L4) with segmented vertebral regions, an associated fracture risk graph plotting BMD against age, and a quantitative 'Results Summary' table. The highlighted total T-score of -5.1 for the lumbar spine is significantly below the -2.5 threshold, indicating severe osteoporosis. The right panel displays the proximal femur (hip) with demarcated regions for the femoral neck, trochanter, and intertrochanteric area. Its corresponding fracture risk graph shows a data point deep within the red 'High Risk' zone. The summary table for the femur highlights a total T-score of -3.8, confirming a diagnosis of osteoporosis. Both panels include Z-scores, peak reference percentages (PR), and age-matched percentages (AM). This comparison chart illustrates diagnostic imaging and metabolic bone disease assessment for clinical education on osteoporosis classification and fracture risk stratification.

This dual-panel image demonstrates body composition analysis using Dual-Energy X-ray Absorptiometry (DEXA). Figure 1a displays two total-body DEXA scans illustrating different phenotypes: a lean individual on the left with high bone-to-soft-tissue contrast, and an individual with higher fat mass on the right where soft tissue obscuration reduces bone clarity. Color-coded Regions of Interest (ROI) are highlighted on the right-hand figure: a blue rectangular box designates the android region (abdominal/L1–L4 area), and a red trapezoidal box indicates the gynoid region (hip and upper thigh area). Figure 1b provides a cross-sectional anatomical diagram of the android region to differentiate adipose tissue compartments. It distinguishes visceral adipose tissue (labeled 1), depicted as pink internal masses located deep within the abdominal cavity near the viscera and spine, from subcutaneous adipose tissue (labeled 2), shown as a peripheral blue/yellow layer situated immediately beneath the skin. This visual illustrates clinical methods for assessing regional fat distribution and metabolic risk markers like VAT in patients with conditions such as COPD or obesity.

This diagnostic image is a transverse axial CT scan of the abdomen at the L3/L4 lumbar level, demonstrating densitometric quantification for body composition analysis. The image shows a cross-section of abdominal viscera, including the kidneys, intestines, and the lumbar spine. A specific region of interest (ROI) has been processed using thresholding (-190 to -30 Hounsfield Units) to identify adipose tissue. Areas highlighted in pink represent the Inter-Muscular Fat Area (IMFA) and subcutaneous adipose boundaries. These pink markings are visible within the posterior muscle compartments (including the erector spinae and psoas muscles) and along the inner fascia of the abdominal wall. This quantitative imaging technique is used in clinical research to assess muscle quality, myosteatosis, and overall metabolic health by isolating fat deposits within skeletal muscle groups, which are distinguished from lean muscle mass and visceral fat.

This diagnostic image display consists of eight whole-body dual-energy X-ray absorptiometry (DEXA) scans categorized by age (Young vs. Old) and Body Mass Index (BMI). The series illustrates variations in body composition across a spectrum ranging from underweight to obese. A standardized color-coding system is used to visualize tissue types: blue represents bone mineral density, red indicates lean soft tissue (muscle), and yellow signifies adipose (fat) tissue. The 'Young' cohort (A-D) shows a progression from a predominance of red and blue with minimal truncal yellow in the underweight scan (BMI 16.9) to extensive, diffuse yellow adipose deposition throughout the trunk and extremities in the obese scan (BMI 48.1). The 'Old' cohort (E-H) demonstrates similar adiposity trends but visually reflects age-related changes, such as potential sarcopenia and altered fat distribution. These scans are used in clinical and educational settings to assess metabolic health, sarcopenic obesity, and the impact of aging on musculoskeletal integrity. The visuals provide a clear comparison of how BMI and chronological age influence the ratio and anatomical distribution of fat, lean mass, and bone.

Diagnostic axial CT scans of the abdomen at the level of the umbilicus, demonstrating body composition segmentation for clinical analysis. The four-panel image (a-d) illustrates different adipose and lean tissue compartments highlighted using Hounsfield unit (HU) thresholding. Panel (a) shows the isolated skeletal muscle mass (SMA), including the abdominal wall and paraspinal muscles. Panel (b) highlights the visceral fat area (VFA) in green, located within the abdominal cavity and surrounding the internal organs. Panel (c) highlights the subcutaneous fat area (SFA) in green, representing the adipose tissue layer directly beneath the skin. Panel (d) shows the total fat area (TFA), combining both visceral and subcutaneous compartments. This radiological segmentation is used to calculate indices like the skeletal muscle index (SMI) and to assess for conditions such as sarcopenia, obesity, or sarcopenic obesity, which serve as prognostic markers in surgical and oncological contexts.

This diagnostic image is an axial CT scan of the abdomen at the L3 vertebral level, processed using sliceOmatic® software for body composition analysis. The image utilizes a pseudocolor segmentation scheme to differentiate tissue types: teal/blue represents subcutaneous adipose tissue (SAT) forming the outer peripheral layer; red indicates skeletal muscle (SM) including the abdominal wall and paraspinal muscles; yellow identifies visceral adipose tissue (VAT) distributed within the abdominal cavity; and green highlights intramuscular adipose tissue (IMAT) located within the muscle boundaries. The L3 vertebral body is visible posteriorly in grayscale. The image serves as an educational tool for quantifying fat and lean mass, often used in clinical research to study metabolic health, obesity, and systemic inflammation (e.g., CRP correlation). The spatial distribution clearly delineates the anatomical boundaries between external fat, the muscular envelope, and internal organ-associated fat.

This diagnostic report displays a dual-energy X-ray absorptiometry (DEXA) scan of the lumbar spine (L1-L4) and its corresponding analytical data. The visual includes an anteroposterior (AP) bone mineral density (BMD) image showing the vertebral bodies L1 through L4, each segmented by rectangular regions of interest for quantitative analysis. To the right, a reference graph plots the patient's BMD (0.710 g/cm²) against age-matched and young-adult (YA) population norms. The graph features color-coded zones: green for normal, yellow for osteopenia, and orange/red for osteoporosis. The patient's data point is notably positioned in the orange zone, indicating significantly reduced bone density. Below the graph, a results table summarizes the findings: a BMD of 0.710 g/cm², a T-score of -3.5 (standard deviations below the YA mean), and a Z-score of -3.7 (standard deviations below the age-matched mean). These findings are clinically indicative of severe osteoporosis or metabolic bone diseases such as osteomalacia, highlighting a high risk for insufficiency and compression fractures.

This diagnostic report presents results from a dual-energy X-ray absorptiometry (DEXA) scan used for bone mineral density (BMD) assessment. The report is divided into two main sections: the Anteroposterior (AP) Lumbar Spine (L1-L4) and the Femoral Neck. Each section includes a localized scan image with defined regions of interest, a color-coded reference graph, a longitudinal trend plot, and a data table. The color-coded reference graphs plot the patient's YA T-score and Z-score against age-matched reference ranges, with green representing normal density, yellow/orange for osteopenia, and red for osteoporosis. For the AP Spine, the table indicates a combined L1-L4 T-score of -2.3 and a BMD of 0.904 g/cm², while the Femoral Neck shows a T-score of -1.7 and a BMD of 0.779 g/cm². These findings are clinically significant for the diagnosis of osteopenia, approaching the threshold for osteoporosis in the lumbar region. The longitudinal 'Trend' graphs track the percentage change vs baseline over time, serving as a tool for monitoring disease progression or treatment efficacy in skeletal health management.
