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.

25% of patients undergoing transthoracic needle biopsy experience complications

Higher complication rates were observed in inpatient settings and in patients with COPD. Also associated with increased adverse events were prior lung cancer screening and the use of oral anticoagulants or antiplatelets.

We can now diagnose Alzheimer's using only an MRI and an algorithm

Encouragingly, the MRI scans did not require the latest equipment advances and were conducted on a standard machine that is readily available at most hospitals—a 1.5 Tesla.

Do race and ethnicity impact the accuracy of diagnostic mammograms?

There are many known disparities in breast imaging that have been found in previous studies, but insight into diagnostic mammography processes is still lacking.

The benefits of preoperative prostate MRI are clear, so why isn't every man getting one?

Preoperative MRI use increased substantially from 2003 to 2016—from 2.9% to 28.2% to be exact—but the modality remained underutilized in certain regions and among specific populations in the United States.

Researchers have designed a new cardiac SPECT imaging system that could potentially deliver images much faster than current models. The team presented its findings at the annual meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI), SNMMI 2022.

The need for speed: New-look cardiac SPECT imaging system could be up to 100 times faster than current models

Researchers presented their proposed design of a self-collimating SPECT system at SNMMI 2022.

A comparison of standard 2D mammography (right) and digital breast tomosynthesis (DBT), or 3D mammography (left). The DBT creates a data set of 1 mm slices that the radiologist can look through to see more detail in suspect areas and determine if it dense breast tissue is masking a tumor.

DBT is better for women with increased breast cancer risks

For the research, special attention was paid to women with dense breasts and other factors that raise their risk of a breast cancer diagnosis.

ACR: FDA evidence backing thyroid monitoring in peds after ICM use is 'weak'

The ACR statement also brought to light some of the unintended consequences of the FDA’s contrast media safety warning.

Targeted radionuclide alpha therapy study wins SNMMI's Abstract of the Year

The study touts the benefits of targeted radionuclide alpha therapy for patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) who have not had success with other treatments.

Around the web

RBMA President Peter Moffatt discusses declining reimbursement rates, recruiting challenges and the role of artificial intelligence in transforming the industry.

Deepak Bhatt, MD, director of the Mount Sinai Fuster Heart Hospital and principal investigator of the TRANSFORM trial, explains an emerging technique for cardiac screening: combining coronary CT angiography with artificial intelligence for plaque analysis to create an approach similar to mammography.

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.
