I now have a comprehensive collection of high-quality MRI wrist anatomy images from the textbook. Let me present them all with proper context.

MRI Wrist Joint Anatomy - Textbook Images

All images are from Imaging Anatomy: Text and Atlas, Volume 3 - Bones, Joints, Vessels and Nerves (Chapter 17: Wrist).

1. TFCC - Coronal & Axial MRI (Fig. 17.35)

Triangular Fibrocartilage Complex - Serial coronal and axial MRI

Fig. 17.35 - Triangular fibrocartilage (TFC) serial coronal images (a-e) from dorsal to palmar, and axial MRI (f, g). Key structures labeled:

TFC proper (star) attaching to the sigmoid notch of the distal radius
Proximal (arrowhead) and distal (thick arrow) laminae attaching at the fovea and ulnar styloid
Lunate, Triquetrum, ulnotriquetral ligament (image e)
Axial views: ECU tendon, fovea, ulnar styloid (S), dorsal radioulnar ligament (dRUL), volar radioulnar ligament (vRUL), ligamentum subcruentum (LS)
Meniscus homologue (MH), ulnar collateral ligament (UCL)

2. TFCC - MRI Coronal Detail (Fig. 17.35a-b)

TFCC MRI coronal views showing sigmoid notch, ECU, fovea, meniscus homologue

Fig. 17.35 (a, b) - Close-up coronal MRI views:

(a): Sigmoid notch, ECU tendon, ligamentum subcruentum (LS), ulnar styloid (S), with the proximal lamina (arrowhead) and TFC proper (blue arrow)
(b): Meniscus homologue (MH), ulnar collateral ligament (UCL), fovea - showing the precise distal insertion of the TFCC

3. TFCC - Coronal Section Anatomy Diagram (Fig. 17.34)

TFCC coronal anatomy diagram showing articular disk, laminae, ulnar fovea

Fig. 17.34 - Labeled coronal section showing the full TFCC architecture: articular disk, proximal (upper) and distal (lower) laminae, meniscus homologue, ulnar collateral ligament, ECU tendon sheath, prestyloid recess, hyaline cartilage, ulnar fovea, and the ulnar head.

4. Wrist Cross-Section - Tendons, Nerves & Compartments (Fig. 17.50)

Axial cross-section of the wrist showing all 6 extensor compartments, carpal tunnel, and neurovascular structures

Fig. 17.50 - Labeled axial cross-section at the level of the distal radius (R) and ulna (U), showing:

6 extensor compartments (dorsal): EPB/APL (1), ECRL/ECRB (2), EPL (3), Extensors 2-4 (4), EDM (5), ECU (6)
Lister's tubercle separating compartments 2 and 3
Volar structures: FPL, FCR, Median nerve, FCU, Radial artery, Ulnar artery & nerve
Space of Parona (deep palmar space)

5. Wrist MRI - Coronal Overview & ECU Tendinosis (Fig. 17.64)

Coronal and axial MRI of wrist showing ECU tendinosis with labeled structures

Fig. 17.64 - Coronal (a) and axial (b, c) proton density MRI views:

(a) Coronal view: All 8 carpal bones clearly visible in their natural arrangement (scaphoid, lunate, triquetrum, pisiform in proximal row; trapezium, trapezoid, capitate, hamate in distal row); radiocarpal joint space well-defined
(b, c) Axial views: ECU tendon at the ulnar groove with surrounding signal changes

6. De Quervain's Tenosynovitis - Axial MRI (Fig. 17.63)

Axial fat-saturated MRI showing de Quervain's tenosynovitis of first extensor compartment

Fig. 17.63 - Axial fat-saturated T1W (a) and fat-saturated proton density (b) MRI demonstrating the first extensor compartment (EPB and APL tendons) and tenosynovitis appearance. Note: While this shows pathology, it clearly demonstrates normal axial MRI wrist anatomy including the round tendon cross-sections.

7. Guyon's Canal (Ulnar Tunnel) - Serial Axial MRI (Fig. 17.53a)

Serial axial MRI of ulnar tunnel showing ulnar nerve, artery, and pisohamate hiatus

Fig. 17.53 (a) - Serial axial MRI from proximal to distal through Guyon's canal:

Red arrows: Ulnar artery (thick = main; thin short = superficial branch; thin long = deep branch)
Blue arrows: Ulnar nerve (thick = main; thin = superficial/motor branches)
P = pisiform, H = hook of hamate, Hiatus = pisohamate hiatus
PCL (palmar carpal ligament), FCU, FDM (flexor digiti minimi), AbDM (abductor digiti minimi), PB (palmaris brevis), PHL (pisohamate ligament)

8. Guyon's Canal - Serial Coronal MRI (Fig. 17.53b)

Coronal MRI series of Guyon's canal showing ulnar nerve and artery course

Fig. 17.53 (b) - Serial coronal MRI views showing the deep motor branch of the ulnar nerve (blue arrows) and superficial branch, the pisohamate hiatus (Hiatus), AbDM, FDM, PHL structures, with pisiform (P) and hamate (H) landmark bones clearly visible.

Summary of Key MRI Wrist Anatomy Structures

Structure	Best MRI Plane	Sequence
TFCC / TFC proper	Coronal	PD or T2 fat-sat
Carpal ligaments (SLL, LTL)	Coronal	PD fat-sat
Extensor compartments	Axial	T1 or PD
Carpal tunnel (median nerve)	Axial	T1 or PD
Guyon's canal (ulnar nerve/artery)	Axial + Coronal	T1
Radioulnar ligaments (DRUL/VRUL)	Axial	PD fat-sat
Carpal bones (osseous anatomy)	Coronal	T1
