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.

'Desktop' MRI brings physics education to the classroom
The tabletop scanner provides students with more hands-on opportunities to learn about the processes that drive the modality’s imaging capabilities.
MRI-first approach could allow many to safely forego prostate biopsy
New findings indicate as many as 96% of men with positive PSA labs who show insignificant or slow-growing cancer on MRI can safely forego biopsy for three or more years.
U.S. moves closer to establishing domestic supply of Mo-99 for nuclear imaging

New algorithm is twice as accurate at predicting stroke timing compared to the standard of care
Determining stroke onset is critical for management, as there is a small window of time for initiating treatment that can inhibit damage.

Preclinical cancer therapy leads to shrinking neuroblastoma

A cell protein known as MYCN (v-myc avian myelocytomatosis oncogene), one of a group of proteins that spur cellular proliferation, is known to be very resistant to even targeted drug treatments, but preclinical research is turning this protein on itself to fight off new neuroblastoma cancer growth, the Dana Farber Cancer Center and Boston Children’s Hospital announced today.
