Coronary CTA With ASIR Can Reduce Risk Of Radiation Exposure By 27%

Using the new coronary CTA (CT Angiography) image enhancement technique called adaptive statistical iterative reconstruction (ASIR) can reduce the risk of radiation exposure by 27%, as reported by a new study published in the September issue of the American Journal of Roentgenology (AJR) and entitled “Adaptive Statistical Iterative Reconstruction: Assessment of Image Noise and Image Quality in Coronary CT Angiography”.

Study Investigates The Credibility Of Radiologists As Paid Witnesses In Legal Cases

A study aims to investigate the credibility of testimony by radiologists who testify at a legal case was published in the August edition of the American Journal of Roentgenology (AJR). The study revealed that paid radiology expert witnesses testimonies do not match with the interpretations of radiologists blind to the court case. Semelka, Ryan, Yonkers, and Braga conducted this study, entitled “Objective Determination of Standard of Care: Use of Blind Readings by External Radiologists”, to determine whether the paid expert witness’ findings of a radiologist in one case commensurate with the findings of radiologists blinded to the clinical outcomes and litigation issues.

ASIR Significantly Reduces Radiation During Abdominal CT

According to a recent study, using a new low dose abdominal CT technique, called adaptive statistical iterative reconstruction (ASIR), can reduce radiation doses delivered during abdominal CT scans by 23-66%. The study will be highlighted in the September issue of the American Journal of Roentgenology. Abdominal CT scans are used mainly for diagnosing the reason of pain in the abdomen or pelvis, in addition to detection of diseases in several abdominal organs such as bowel and colon. ASIR is a recently developed, low dose CT technique that permits radiologists to reduce noise in image while improving its quality, the technique also reduces the delivered radiation doses.

Whole Body MRI To Detect Child Abuse In Infants

According to a new study, whole-body magnetic resonance imaging (MRI) can be used for detecting child abuse in infants. MRI is well-known for its accuracy and high-detailed images. The study appears in the September issue of the American Journal of Roentgenology. Whole-body MRI features high safety profile as the technique does not involve using radiation to generate images; instead, it uses a magnetic field, radio frequency pulses, and a computer to produce its images of internal organs, bones and other musculoskeletal structures. Diagnosing abuse depends mainly on detecting skeletal injuries, along with using high-quality skeletal surveys to detect any high-specificity fractures that might be seen in cases of infant abuse. However, subcutaneous tissue and muscle injuries are not currently evaluated with imaging techniques in living children.

ASIR Offers New Options For Colonography

According to a new study, using adaptive statistical iterative reconstruction (ASIR), a new low dose CT procedure, offers assistance to radiologists in decreasing the currently reduced radiation dose delivered while conducting CT colonography (CTC) by about additional 50%. The study was published in the July issue of the American Journal of Roentgenology.
