Dramatic advances in diagnostic radiology continue. It was noted in last year's CONTEMPO that the most important developments were related to interventional radiology, ultrasonography, computed tomography (CT), nuclear radiology, nuclear magnetic resonance (NMR), positron emission tomography (PET), and computed digital radiography (CDR). This statement is still true a year later. In this presentation, clinical aspects will be emphasized and technical descriptions will be limited because of requirements of space.

Interventional Radiology 

Percutaneous Transluminal Angioplasty.—  Percutaneous transluminal angioplasty (using a balloon of appropriate diameter to widen the lumen of an artery) has now been applied successfully to the popliteal, femoral, iliac, renal, carotid, vertebral, and subclavian arteries. Follow-up studies are being reported with increasing frequency. Considerable success in iliac artery angioplasty is reported, with higher recurrence rates in femoral, popliteal, renal, and coronary angioplasties. Redilation is often possible.Coronary artery angioplasty, considered experimental until recently, is undergoing successful developments in several
