Diagnostic Imaging

Radiologists use diagnostic imaging to non-invasively look inside the body to help determine the causes of an injury or an illness, and confirm a diagnosis. Providers use many imaging modalities to do so, including CT, MRI, X-ray, Ultrasound, PET and more.

Illustration of the four types of breast tissue densities. The more dense, the harder it is for radiologists to detect cancers, which had led to about 40 states to now require notiofication of patients if they have dense breasts and the impact on their care, with possible miss-reads and that they may need supplemental imaging.

Chest X-ray. Using an explainable artificial intelligence (AI) model, researchers were recently able to accomplish highly accurate labeling on large datasets of publicly available chest radiograph X-rays.. 

Chest X-ray guidelines disappoint in the ED

At one institution, the guidelines are not as effective as many had hoped, according to new post-implementation data.

FAPI PET/CT shows promise as a better radiotracer for cancer than 18F-FDG. It also can be used for detection of infection and inflammation.

VIDEO: 6 key advances in molecular imaging technology for PET and SPECT

Munir Ghesani, MD, President of the Society of Nuclear Medicine and Molecular Imaging (SNMMI), system chief of nuclear medicine at Mount Sinai Health, explains recent advances in nuclear imaging technology.

Improving the diagnostic value of portable imaging: Experts propose 3 interventions

After experts from one institution evaluated 500 portable chest x-rays completed during the summer of 2021, it was revealed that 46.2% of the images obtained were problematic, requiring the imaging to be repeated.

Comparison of flurpiridaz F-18 PET, SPECT and angiography of the 60-year-old female patients in the Aurora trial. The SPECT scan appeared normal, but flurpiridaz was shown to be more sensitive and showed the ischemia from two blockages in the right coronary artery. The new radiotracer may help expand cardiac PET. #ASNC

Flurpiridaz data shows promise to expand and enhance cardiac PET

The biggest news from the American Society of Nuclear Cardiology (ASNC) 2022 meeting was positive late-breaking data on the phase 3 Aurora trial for the flurpiridaz (F-18) PET radiotracer agent.

soft tissue lymphoma versus soft tissue tumor

Soft tissue lymphomas versus soft tissue tumors: MRI features reliably differentiate between the two

A new analysis offers a detailed comparison of soft-tissue lymphomas and soft-tissue tumors based on imaging characteristics from MRI scans—an area of study that has not yet been rigorously explored, the authors of the paper indicated.

Photon-counting CT/AI combo improves multiple myeloma detection

When combined with artificial intelligence-based noise reduction techniques, new photon-counting CT technology can increase the detection of bone disease while also decreasing radiation exposure.

bone and soft tissue tumors

Radiologists' understanding of tumor 'mimics' vital when assessing bone and soft tissue lesions

Authors of the new EJR paper explained that, although most of these tumors present in a similar way—with a lump or localized pain—their origins are wide-ranging and require the use of additional imaging to characterize the lesion.
