Radionuclide angiography of azygos continuation of inferior vena cava in left atrial isomerism (polysplenia syndrome).
Interruption of the inferior vena cava with azygos continuation is present in at least 65% of the patients suffering from left atrial isomerism (polysplenia syndrome). First-pass radionuclide angiography using a peripheral vein of the foot correctly diagnosed interruption of the inferior vena cava in seven patients. ⋯ Four underwent surgical correction (or palliation), three are waiting for an operation. Radionuclide angiography is a simple outpatient procedure and useful in the clinical diagnosis of this syndrome.

Case ReportsHematologic depression following therapy with strontium-89 chloride.
Initial clinical trials using strontium-89 (Sr-89) chloride for the treatment of painful skeletal metastases have observed minimal or no hematological depression secondary to the radiostrontium. A patient with marked bone marrow depression temporally related to the administration of the Sr-89 is reported, and the need for close hematological monitoring is emphasized. Bone marrow tumor replacement may predispose patients to marrow depression from radiostrontium, and such patients should be treated with caution.

Adherence of radiopharmaceuticals and labeled cells to intravenous tubing.
A survey of 67 nuclear medicine departments revealed no agreement on which radiolabeled agents could be injected through intravenous lines (IVs) and which required direct venipuncture. Labeled cells and several common radiopharmaceuticals were tested for adherence to intravenous tubing. Residual activity remaining in the tubing after an adequate flush was less than 1% of the injected dose in each case. Administration of radiolabeled agents through existing IVs is an acceptable alternative to direct venipuncture in many cases.

Case ReportsLymphoscintigraphy in patients with lymphedema. A new approach using intradermal injections of technetium-99m human serum albumin.
Forty cases were examined by a new lymphoscintigraphic approach using intradermal injections of Tc-99m human serum albumin (HSA). Thirty-three patients had lymphedema due to the metastases of a malignant tumor and/or the dissection of lymph nodes. The others were control patients without lymphedema. ⋯ These abnormalities were observed in a high percentage of patients with moderate lymphedema, as compared with a low percentage of patients with slight lymphedema. The collateral pathways could not be observed in patients with severe lymphedema. Imaging with Tc-99m HSA was considered to be more useful than other techniques, including radiocolloid lymphoscintigraphy, for examining patients with lymphedema.
