Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT.

Observation times following renal biopsies can be significantly reduced, according to new research

New findings indicate that monitoring times following renal mass biopsy could be revisited in many cases without posing risks to patients.

New data suggest clinicians should think twice before foregoing contrast-enhanced imaging

The new data highlight a potential pitfall of unenhanced CT scans on patients presenting to emergency departments with acute pain—an inaccurate workup.

Learning app improves reader performance for prostate MRI

Interactive teaching app improves reader performance on prostate MRI

Experts involved in the app’s creation suggested that because it was designed to mimic real life, its use among emerging radiologists could potentially help address the issue of subjectivity and reader variability in interpreting mpMRI scans of the prostate.

How 'mindlessly' following AI guidance impacts radiologist performance

Radiologists interpreting screening mammograms may be especially susceptible to falling victim to automation bias, as these exams are repetitive in nature.

Breast cancer risk assessments should account for longitudinal changes in breast density, new data suggest

Breast density is known to drop over time, but the rate at which density decreases merits special attention, as it could be associated with a woman’s chance of developing cancer.

Radioactive substances unnecessary in new method for measuring brain glucose metabolism

Rather than administering radiolabeled glucose for exams, imagers give patients a small amount of a harmless glucose solution that is said to be equivalent to a can of a carbonated drink.

X-ray photon trajectory during the simulation phantom study from the side and top views. Due to scattering of the X-rays when they hit the lower end of the patient bed, exposure in mainly to the lower body of the interventional echocardiographer performing transesophageal echocardiography. The green lines are the scattered photon trajectories calculated by Monte Carlo simulation in the study.

Radiation exposure in the cath lab: Tracking the impact on interventional echocardiographers

Researchers found that echocardiographers in the cath lab are exposed to high doses of radiation on the right half of their body, especially the waist and lower body. 

Around the web

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease. 

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care.
