Nuclear medicine and ultrasound; correlation in diagnosis of disease of liver and biliary tract

Abstract

Even though the radiocolloid scan is nonspecific it will be approximately 70%-80% accurate in predicting the presence or absence of liver disease and somewhat less accurate than that in making statements as to the specific type of disease. This compares well with other modalities. The ability of nuclear medicine techniques to provide a correct diagnosis is improved when additional isotopic techniques such as hepatic blood flow studies and 131I-rose bengal and 67Ga scanning are performed. Ultrasound scanning is also non specific. To date, the major application of ultrasound in the study of the liver has been in deciphering puzzling contour abnormalities seen on nuclear medicine scans and in demonstrating fluid-filled abnormalities. Its usefulness in diffuse and solid focal lesions has been less dramatic. More recently, however, the development of gray scale has necessitated a reevaluation of the technique. Gray scale demonstrates a large number of intrahepatic interfaces that were previously invisible, and it has already been shown to demonstrate focal disorders such as metastasis more easily than the nongray-scale method. It can also demonstrate dilated biliary radicals, the gallbladder, and gallstones. In addition, while routi...Continue Reading

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.
