To evaluate the technical success and immediate complication rates of temporary internal jugular vein (IJV) haemodialysis catheter placement in normal and high-risk patients. ⋯ Ultrasound-guided placement of internal jugular vein catheters is very safe with very high success rate and few complications. It can safely be performed in high-risk patients, like patients with disorders of haemostasis and patients with previous multiple catheter insertion in the same vein.

In patients with macroadenoma, posterior pituitary high signal (PPHS) on T1-weighted magnetic resonance (MR) imaging is sometimes observed in an ectopic location. The present study compared incidences of ectopic PPHS before and after macroadenoma surgery using MR imaging, including dynamic MR imaging to ascertain whether this ectopic change is irreversible. ⋯ Greater volume of adenoma is associated with a higher incidence of ectopic PPHS, and the ectopic change is irreversible.

Comparative Study
A comparative study to validate the use of ultrasonography and computed tomography in patients with post-operative intra-abdominal sepsis.
To validate abdominal ultrasonography and helical computed tomography in detecting causes for sepsis in patients after abdominal surgery and to determine improved criteria for its use. ⋯ Computed tomography can be used as the imaging modality of choice in patients suspected of intra-abdominal sepsis after abdominal surgery. Because of the low discriminatory power ultrasonography should not be performed as initial diagnostic test.

To correlate MR and CT discography findings with pain response at provocative discography in patients with discogenic back pain. ⋯ Typical MR findings with concordant pain at discography include grade 4 or 5 disc degeneration and presence of a high intensity zone. Typical CT discography findings with concordant pain were fissured/ruptured discs and contrast extending into/beyond the outer annulus on CT.

We have investigated the role of sonography in the diagnosis of plantar fasciitis. ⋯ We conclude that in patients with plantar fasciitis, ultrasound may detect relatively small differences in plantar fascia thickness even in clinically unequivocal plantar fasciitis.
