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.

Hepatobiliary scanning with 99mTc-PIPIDA in acute cholecystitis.
Radiology, 1982Ninety-five patients with clinically suspected acute cholecystitis underwent hepatobiliary scanning with 99mTc-PIPIDA. A positive scan (nonvisualization of the gallbladder with visualization of the common bile duct and gut) was found in 29 patients; 25 of them (86%) had surgically proven acute cholecystitis and 4 (14%) had chronic cholecystitis.

Morphology of skin incubation in Pipa carvalhoi (Anura: Pipidae)
Journal of Morphology, 2009AbstractSouth American Pipidae show a unique reproductive mode, in which the fertilized eggs develop in temporarily formed brood chambers of the dorsal skin after eggs have been deposited on the back of the female. We studied the skin incubation of Pipa carvalhoi using light microscopy and scanning electron microscopy. The skin consists of a stratified

Acute effects of nicotinic acid on hepatic transport of 99mTc-PIPIDA
European Journal of Nuclear Medicine, 1983Hepatic injury has been associated with nicotinic acid treatment of schizophrenia and hypercholesterolemia. This association was implicated when the liver and biliary tract were not visualized after 99mTc-HIDA in a patient taking 3 g daily of nicotinic acid.

Diagnosis of acute cholecystitis using hepatobiliary scan with technetium-99m PIPIDA
The American Journal of Surgery, 1981Sixty patients were evaluated for acute abdominal pain using technetium-99m PIPIDA hepatobiliary imaging. The sensitivity of the test was 90.6 percent in all patients and the accuracy was 93.3 percent. In the evaluation of acutely ill patients with right upper quadrant pain, fever, nausea and vomiting, hepatobiliary imaging with PIPIDA is the preferred
