Abnormalities involving the musculoskeletal system are numerous and frequent in patients with chronic renal insufficiency (CR1). The most common radiologic manifestations of CR! are those referred to collec

Two hundred and two patients with bone pain from metastatic cancer were treated with 40 , Ci/kg ofSr.89. Patients were followed with pain diaries, records ofmedication taken, sleep patterns, serial bone scans and a Karnofsky Index. One hundred and thirty-seven patients with adequate followup survived at least 3 months, including 100 with prostate and 28 with breast carcinoma. Eighty of the 100 patIents with prostate cancer responded, and 25 ofthe 28 breast cancer patients Improved. Ten patients wIth prostate cancer and five with breast cancer became pain free. Little hematologlc depression was noted. Sr89 kinetic studies showed that strontium taken up in osteoblastic areas remained for 100 days. The tumor#{149}to.marrow absorbed dose ratio was 10:1.

Herniography is an accurate means of identifying groin hernias when the clinical diagnosis is uncertain. Its role in evaluation of other types of ventral hernias is less clear; however, with minor modifications in technique, herniography is also useful in these cases. This article reviews the technique of herniography, normal variations in anatomy, and interpretation of herniograms of the groin and anterior abdominal wall on the basis of 72 patients studied over 3 1/2 years. Herniography is also compared with cross-sectional imaging techniques. Inguinal and femoral hernias are best shown and classified with herniography. Ventral hernias are well demonstrated by both herniography and cross-sectional imaging; however, herniation of only fat and supine imaging may lead to misdiagnosis with computed tomography or ultrasound. Spigelian hernias are probably best depicted with cross-sectional imaging. Diagnostic pitfalls of herniography are reviewed, including the need for obtaining postexercise radiographs, oblique radiographs, and tangential radiographs.
