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.

For monitoring purposes, AI-aided MRI does what liver biopsy does with less risk, lower cost

Patients with autoimmune hepatitis may be better monitored across disease stages by AI-augmented multiparametric MRI than by liver biopsy, as the imaging has proven less costly and is inherently less risky due to its noninvasiveness. 

Representative cases showing pneumonia extents and patterns on chest X-ray (CXRs) and CT images. (E and F) A 36-year-old male with no history of vaccination for COVID- 19. The patient had no history of comorbidity. Axial chest CT image obtained on the same day showing unilateral ground-glass opacity with a nonrounded morphology and non-peripheral distribution in the left upper lobe (arrows). RSNA Image. COVID on X-ray, CT scan. What does COVID look like in medical imaging? Example of COVID imaging.

Vaccinated vs unvaccinated, Delta vs Omicron—how do these factors impact clinical and imaging features?

Vaccination rates likely had a role in reducing disease severity during Omicron, a new paper published in Radiology suggests.

Targeted outreach needed in socially vulnerable areas with low cancer screening rates

Social vulnerability index scores account for factors like socioeconomic status, household composition, disability, minority status, language, housing type and transportation.

New recommendations for cardiac CT in cardio-oncology imaging

The statement was written to fill gaps in recommendations from prior consensus statements and guidelines in regards to the use of CCT in cardio-oncology, including use of calcium scoring and ruling out coronary disease when cardiac function is impaired.

Experts call for guidelines limiting interpretations during busy shifts, citing a reduction in error rates

When exam volumes increase, so too does the risk of diagnostic errors in interpretations, many of which can be clinically significant.

On review, popular imaging decision aid earns 1 thumbs-up—with caveats

With 91% sensitivity but only 25% specificity, the tool is worthwhile for clinicians who remain wary of frequent false positives that would send patients with no fractures for unneeded imaging.

Experts concerned with radiation doses in young women call for stricter ordering criteria for CT exams

Experts found that compared to the average effective doses of organs, breast doses were higher, representing increased risks of breast cancer for women. 

Ultrafast MRI protocol reduces scan time by 10 minutes for cervical imaging

Experts involved in the study suggested that the protocol could open doors leading to greater utilization of MRI in the future.
