[Anatomy of the pelvic lymphatic system].

The lymphatic system of the pelvis collects the lymph of the genital and urinary organs and of the digestive tract. It is formed by lymphatic nodes and vessels situated inside the conjunctive tissue, near the organs (visceral lymphatic nodes) but especially along the external, internal and common iliac vessels (iliac lymphatic nodes). These nodes receive afferent vessels issued from the different pelvic organs.

Temporal lobe association fiber tractography as compared to histology and dissection.

Objectives: To compare the temporal lobe white matter fiber bundles obtained by diffusion tensor imaging-based tractography to that by histology and dissection, and to study the interindividual variability of the obtained tracts.

Materials And Methods: DTI (diffusion tensor imaging) acquisitions (30 directions) were obtained from nine healthy volunteers. Imaging post-processing was performed with FSL (FMRIB Software Library) software.

Scaphotrapezial ligament: normal arthro-CT and arthro-MRI appearance with anatomical and clinical correlation.

The purpose of our study was to demonstrate and describe the MR and arthro-CT anatomic appearance of the scaphotrapezial ligament and illustrate some of the pathologies involving this structure. This ligament consists of two slips that originate from the radiopalmar aspect of the scaphoid tuberosity and extend distally, forming a V shape. The ulnar fibers, which are just radial to the flexor carpi radialis sheath, inserted along the trapezial ridge.

[The spinal canal: from imaging anatomy to diagnosis].

The spinal canal is divided into epidural, subdural and subarachnoid spaces. Intraspinal processes should be correctly placed into their space of origin. MRI is the best imaging modality to achieve this task.
