To retrospectively evaluate the clinical outcome of non-anticoagulated patients with clinically suspected acute pulmonary embolism (PE) and no symptoms or signs of deep venous thrombosis (DVT) following a negative contrast medium-enhanced spiral CT of the pulmonary arteries (s-CTPA). ⋯ Patients with clinically suspected acute PE, no symptoms or signs of DVT and a negative single slice s-CTPA using 3-5 mm collimation, may safely be left without anticoagulation treatment unless they are critically ill, have a limited cardiopulmonary reserve and/or if a high clinical suspicion remains.

Our goal was to prospectively study the therapeutic efficacy of CT-marking and fluoroscopy-guided intraarticular corticosteroid instillation of inflamed sacroiliac joints in patients with ankylosing spondylitis. ⋯ CT-marking and fluoroscopy-guided intraarticular corticosteroid instillation in the sacroiliac joints may be regarded as an effective therapy. This technique was useful, rapid and safe.

To find a suitable high-resolution MR protocol for the visualization of lesions of all 12 cranial nerves. ⋯ A combination of 3D CISS, the 2D T1-weighted fat suppressed sequence and a 3D contrast-enhanced MP-RAGE proved to be the most useful sequence to visualize all lesions of the cranial nerves. For the determination of enhancement, an additional 3D MP-RAGE sequence without contrast medium is required. This sequence is also very sensitive for the detection of hemorrhage.

To review image-guided chest port insertion using the right internal jugular vein as the access site of choice. ⋯ Image-guided placement of internal jugular vein chest ports has a high success rate and low complication rate compared with reported series of unguided subclavian vein port insertion. The internal jugular vein should be used as the preferred venous access site compared to the subclavian vein.

To determine the severity and extent of emphysema in heavy smokers by high-resolution CT (HRCT) and to correlate the findings with spirometric tests (STs) and symptomatology. ⋯ A significant number of asymptomatic and clinically undiagnosed smokers tend to have significant emphysema. HRCT helps in early detection of disease and thus helps implementation of preventive measures.
