Fortuitous Findings of Tc-99m PIPIDA Hepatobiliary Scintigraphy
Clinical Nuclear Medicine, 1982Hepatobiliary scintigraphy using Tc-99m labeled radiopharmaceuticals is employed primarily for the diagnosis of acute cholecystitis and for demonstration of biliary tract potency. This produce may also provide diagnostic information in the identification of unusual or atypical hepatobiliary disorders; frequently, this occurs as an incidental result of ...

Effect of fasting and parenteral alimentation on PIPIDA scintigraphy
Digestive Diseases and Sciences, 1983Ten patients were prospectively studied using 99mTc-PIPIDA imaging to evaluate the effects of fasting and parenteral alimentation on gallbladder function. Three of ten patients had initial nonvisualization of the gallbladder for up to 2 hr, yet had normal visualization on repeat imaging performed after resumption of oral intake or after parenteral ...

Mating Behavior of Xenopus wittei (Anura: Pipidae)
Copeia, 1997Pipa pipa, now well known for its development of young in pockets on the mother's back (Rabb and Snedigar, 1960). Rabb and Rabb (1960) reported the first descriptions of spawning in P. pipa, including egg laying during midwater somersaults. The "turnover" was initiated by the female and described as a "sideways upward movement, a momentary pause in a ...

Osteocyte lacunae size in the genus Xenopus (Pipidae)
Amphibia-Reptilia, 1987AbstractThe relationship is studied between the volume of osteocyte lacunae and the nuclear DNA content and level of ploidy in the genus Xenopus. The lacunae volume and the DNA content appear strongly correlated. The possible use of this relationship in the study of the evolution of the genus is discussed.

PIPIDA scan diagnosis of traumatic rupture of the gallbladder
Injury, 1985Eighteen days after injury, a patient was evaluated for bilious ascites with a 99mTc-PIPIDA (paraisopropyliminodiacetic acid) scan. A ruptured gallbladder was shown, and this finding was confirmed at exploration. Radionuclide scanning offers a sensitive, non-invasive approach for delineating disruption of the biliary tract, and should be considered ...

Biliary excretion disorders in infants: evaluation using 99mTc PIPIDA
American Journal of Roentgenology, 1980A new class of hepatobiliary imaging agents has become available--the N-substituted iminodiacetic acids. After intravenous administration, these compounds are quickly extracted by the hepatocytes and rapidly excreted into the biliary tree. By using a 99mTc label, sufficient activity may be given to allow excellent gamma-camera imaging, 99mTc-labeled p ...

99m Tc-PIPIDA Cholescintigraphy in the Diagnosis of Gallbladder Disease
The American Journal of the Medical Sciences, 1982The efficacy of 99mTc cholescintigraphy in the diagnosis of gallbladder disease was studied in 116 patients. Sixty-one demonstrated gallbladder visualization (normal) and 55 had nonvisualization. In patients with acute abdominal pain, test sensitivity is 100%, specificity is 77%, and accuracy is 83% for the diagnosis of acute cholecystitis; no patient ...

Imaging Patterns With 99mTc-PIPIDA in Evaluating Abdominal Pain
Southern Medical Journal, 1983A random retrospective review of hepatobiliary scans on 86 adult patients with abdominal pain revealed four distinct imaging patterns: normal, cystic duct obstruction, obstructive, and sick liver pattern. A normal pattern was found to exclude acute cholecystitis and was the pattern most frequently observed.

Diagnostic Accuracy of Hepatobiliary Scintigraphy with 99mTc-PIPIDA Questioned
Pediatrics, 1981Majd et al (Pediatrics 67: 140, 1981) refer to hepatobiliary scintigraphy with 99m-labeled p-isopropylacetanilido iminodiacetic acid (99mTc-PIPIDA) as a highly accurate test for differentiating biliary atresia from other causes of neonatal jaundice. We agree that this technique is superior to rose bengal.

Gastrobiliary fistula: pre- and postoperative assessment with 99mTc-PIPIDA
American Journal of Roentgenology, 1981Demonstration of bile leakage through fistulas with hepatobiliary radiopharmaceuticals was first done with /sup 131/I rose bengal. The improved anatomic detail provided by technetium-99m-labeled iminodiacetic acid compounds gives more detailed information.
