Absence of thyroid stunning after diagnostic whole-body scanning with 185 MBq 131I.

Unlabelled: There has been recent controversy regarding the optimal protocol for imaging and ablation of post-thyroidectomy patients. Several authors have suggested that a scanning dose of 185-370 MBq (5-10 mCi) (131)I may be capable of producing a stunning effect on thyroid tissue that may interfere with the uptake and efficacy of the subsequent ablation dose of radioiodine. The purpose of this study was to determine whether a 185-MBq (5 mCi) diagnostic dose of (131)I produces a visually apparent stunning effect 72 h before (131)I ablation therapy.

Sonography: a useful tool to detect the mechanical causes of renal transplant dysfunction.

Purpose: The purpose of this study was to evaluate the utility of sonography in distinguishing between mechanical and nonmechanical causes for renal transplant dysfunction.

Methods: We reviewed all ultrasound examination reports (n = 286) for 63 consecutive patients who received 64 renal transplants. We assessed the sensitivity and specificity of different degrees of hydronephrosis (mild, moderate, or severe) in detecting urinary tract obstruction; different volumes of new or increasing peritransplant fluid in detecting urine leaks; different total volumes of peritransplant fluid in predicting significant compression of the transplant; and Doppler vascular criteria for predicting arterial and venous occlusion.

Urine leaks in renal transplant patients. Diagnostic usefulness of sonography and renography.

We evaluated the utility of sonography and nuclear medicine renography in the detection of urine leaks in 57 renal transplant patients. Sonography and renography were equally sensitive in detecting leaks. But renography was more specific and therefore accurate (p < 0.

Atypical hyperplasia: frequency and mammographic and pathologic relationships in excisional biopsies guided with mammography and clinical examination.

Purpose: To ascertain the frequency and pathologic relationships of atypical hyperplasia in biopsy specimens obtained after clinical and mammographic examination.

Materials And Methods: Clinical, mammographic, and histologic findings were prospectively correlated in 300 consecutive excisional biopsies.

Results: Atypical hyperplasia was detected in 26 (17%) of 154 biopsies with benign findings and 19 (13%) of 146 biopsies with malignant findings overall (P > .

Abdominal staging of thoracic Hodgkin disease: CT-lymphangiography-Ga-67 scanning correlation.

A retrospective study was performed to assess whether lymphangiography and gallium-67 scanning were complementary to computed tomography (CT) in abdominal staging of disease in 94 patients with early-stage thoracic Hodgkin disease. In 51 patients with surgical or follow-up correlation, the spleen was involved in 16% (n = 8), the spleen and lymph nodes in 22% (n = 11), and only lymph nodes in 2% (n = 1). In these 51 patients, none of the imaging modalities had greater than 50% sensitivity for the detection of nodal involvement.
