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. 

Mediolateral oblique view from a screening mammogram in a 54-year-old woman shows a small cluster of microcalcifications in the upper outer quadrant of the right breast. The right image shows a detailed spot magnification view of the calcifications. Stereotactic biopsy revealed grade 2 ductal carcinoma in situ (DCIS). RSNA image.

Why the way microcalcifications on mammograms are regarded could change

New research suggests that the tissue environment where microcalcifications of the breast are formed could hold clues into how breast cancer progresses.

Focused ultrasound reduces physical symptoms of Parkinson's disease

Given the less invasive nature of focused ultrasound procedures, researchers suggest that it could open the door for disease management options catered to a wider variety of patients.

New practice guidelines for PET imaging of neuroendocrine tumors

Issued by the Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the European Association of Nuclear Medicine (EANM), the new guidelines are intended to inform any practitioners involved in ordering, performing, reading and reporting SSTR PET imaging.

Older women with breast cancer can safely forego radiation therapy

New data suggest that it may not be necessary for women older than 65 with hormone receptor-positive breast cancer to undergo radiotherapy after breast-conserving surgery and hormone therapy, as it does not impact death rates or metastasis risk.

How effective are chest CT severity scores in managing COVID?

While the studies on these systems have proven them to be effective in diagnosing and treating COVID in specific cohorts, the varying settings in which they were used can make it difficult to derive definitive conclusions on their efficacy.
