Cholangiography before biliary surgery: single-shot MR cholangiography versus intravenous cholangiography

Radiology

Abstract

To compare depiction of the biliary tract with magnetic resonance (MR) and intravenous cholangiography before biliary surgery. Intravenous cholangiograms and heavily T2-weighted single-shot MR images in 60 patients with biliary calculi were compared prospectively. Images obtained with each technique were independently assessed for depiction of anatomy and calculi. The gallbladder was adequately visualized with intravenous cholangiography in 77% of patients and with MR cholangiography in 88%. Rates for visualization of the common bile duct were 97% and 100%, respectively; for the cystic duct, 27% and 75%; and intrahepatic ducts, 28% and 77%. With either technique, calculi in the gallbladder were correctly predicted as solitary or multiple in approximately 80% of patients. Five cases of common bile duct calculi were correctly predicted with this technique, two cases with cystic duct calculi were depicted with only MR cholangiography. Single-shot MR cholangiography may replace intravenous cholangiography for visualization of the biliary tract. However, the delineation of tiny gallbladder calculi and shrunken gallbladders with thickened bile is limited.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
