[Modern urography].

An IVP optimum quality should be tailored to the particular needs of a given case and consequently most be supervised by the radiologist when it is being performed. The most meticulous technique is needed, the adequate amount of contrast medium should be used, compression of the ureters should be performed and under optimum conditions tomography during the nephrographic phase should be performed whenever the circumstances should require it. With only very few exceptions no significant differences between different contrast media exist. The use of medium speed high contrast x-ray films as well as the use of rare earth intensifiers screens avoid the need for extremely powerful generators that are very costly. Film processing is a critical step in obtaining a good study and should be automatic.

Unusual complications of renal cyst puncture.

The authors present a case of subcapsular hematoma with compromise of renal function and a case of arteriovenous communication as two infrequent complications of renal cyst puncture.

The clinical significance of dilatation of the collecting system in the transplanted kidney.

The significance of dilatation of the collecting system of the transplanted kidney and its relationship to bladder distention was reviewed in 39 renal recipients examined by sonography (94 studies). The degree of pelvicaliceal (PCS), ureteral, and bladder distention was graded and correlated with the 24-h urine output, nuclear renal scan, and clinical follow-up. marked PCS distention can indicate obstruction (33%), especially when there is no associated bladder distention (60%) and a fluid collection lies along the path of the ureter. The 24-hr urine output did not influence the degree of PCS distention.

Comparison of CT and MR imaging in musculoskeletal neoplasms.

Magnetic resonance (MR) and CT of 50 musculoskeletal neoplasms were compared to investigate the relative values of these modalities in the assessment and staging of musculoskeletal neoplasms and to determine how often they are complementary and when they are redundant. The material included 25 benign and 25 malignant neoplasms, of which 33 were skeletal and 17 were of soft tissue origin. Magnetic resonance was superior to CT with respect to all morphologic criteria except for cortical bone destruction, calcification, ossification, and the assessment of lytic and sclerotic changes in flat bones. Magnetic resonance was found to be complementary to CT in 48% of the cases (30% malignant, 18% benign). Use of both MR and CT was considered redundant in 52% of the cases (20% malignant, 32% benign). Magnetic resonance was found to be the modality of choice for all benign and malignant soft-tissue neoplasms. Both modalities are complementary and necessary for complete evaluation of malignant skeletal tumors. Benign skeletal tumors should be considered for evaluation by CT, MR, or both on an individual case basis.
