The uterine blush. A potential false-positive in Meckel's scan interpretation.

To determine the presence, prevalence, and clinical importance of Tc-99 pertechnetate uterine uptake, this retrospective analysis of 71 Meckel's scans was undertaken. Specifically, each study was evaluated for the presence of a focal accumulation of radiotracer cephalad to the bladder. Patients received an intravenous dose of 150 microCi/kg of Tc-99 pertechnetate. Each study consisted of 15 one minute anterior serial gamma camera images, and a 15, 30, and 60 minute anterior, right lateral and posterior scintiscan. Menstrual histories were obtained from all patients except two. No males (33/33), nor premenstrual (13/13), menopausal (4/4) or posthysterectomy (2/2) patients revealed a uterine blush. Eleven of 15 patients (73%) with regular menses demonstrated a uterine blush. They were in the menstrual or secretory phases of their cycle. Four demonstrated no uterine uptake, had regular periods, but were in the proliferative phase of their cycle. Two with irregular periods, and one with no recorded menstrual history, manifested the blush. Radiotracer should be expected in the uterus during the menstrual and secretory phases of the menstrual cycle. It is a manifestation of a normal physiologic phenomenon, and must be recognized to prevent false-positive Meckel's scan interpretations.

Tc-99m glucoheptonate brain scintigraphy: a clinical comparison between one- and two-hour delayed images: concise communication.

Sixteen patients with known cerebral disease had one- and two-hour delayed brain scans following intravenous injection of 15 mCi of technetium-99m glucoheptonate. No abnormalities were seen on the two-hour images that were not detected on the one-hour delayed scan. There were two false negative scans. Of the 14 true positives, 10 were visualized equally well in the one-and two-hour delayed images, two were better seen on two-hour images, and two were better on one-hour scans. As no difference in lesion detection was found, consideration of reducing the post-dose delay time two hours to one seems warranted.

Hepatobiliary scanning in the diagnosis of acute cholecystitis.

Two hundred seventy-one consecutive hepatobiliary scans (HBS) using technetium Tc 99m iprofenin (Pipida [Sn]) were obtained to evaluate abdominal pain. The material (5 to 10 mCi) was injected and standard anterior and lateral scintographic images were obtained during a one-hour period. An abnormal scan was defined as one in which the gallbladder failed to be seen by one hour with adequate visualization of the biliary tree and proximal gastrointestinal tract. The accuracy of this method was evaluated on the basis of surgical pathology obtained in 117 patients. Of the 76 patients undergoing surgery with an abnormal HBS, 75 had acute cholecystitis, yielding a test accuracy of 98.7%. A normal scan reliably excluded the possibility of acute cholecystitis (100%). Hepatobiliary scanning is presently the most accurate and rapid modality in the diagnosis of acute cholecystitis.

The deltoid tuberosity--a potential pitfall (the "delta sign") in bone-scan interpretation: concise communication.

Evaluation of 100 consecutive technetium methylene diphosphonate bone scintiscans revealed, in seven patients, increased uptake in the upper third of the humeral shaft. Comparison with the radiographs revealed that this corresponded to the presence of a prominent deltoid tuberosity. Though this uptake (the delta sign) is not a common finding, its recognition is important to prevent bone-scan misinterpretations.

Redux testis: a potential pitfall in testicular imaging.

The use of radionuclide testicular imaging to assess testicular perfusion has been shown to be a valuable diagnostic procedure in the evaluation of the acute scrotum. However, if images are not evaluated in conjunction with physical findings falsely negative examinations can occur. A case of torsion of a retractile testicle (redux testis) is presented to demonstrate this potential limitation. To our knowledge this has not been reported previously.

The incidental detection of gallium-67 citrate in a urinoma following a right pyeloplasty: a case report.

An abnormal accumulation of radionuclide was identified within the right juxtadiaphragmatic and juxtahepatic spaces during gallium-67 citrate scintigraphy in a post-pyeloplasty patient. Its mode of presentation, the recent pyeloplasty and the known biologic distribution of gallium suggested that it represented gallium-67 concentration within a postoperatively created urinoma. Diagnosis was confirmed by excretory urography and laparotomy.
