Both MRIs and CT scans are used to create pictures of your organs to help doctors discover and diagnose potentials issues. The main difference between these two sophisticated imaging techniques is that CT (computed tomography) scans use X-rays while MRIs (magnetic resonance imaging) use radio waves. Both of them create detailed images of inner tissues
A lung ultrasound could help physicians quickly determine whether a pregnant woman with preeclampsia is at risk of respiratory failure, according to preliminary research published in Anesthesiology. About 60,000 women worldwide die as a result of preeclampsia, which causes severely high blood pressure. Potential complications include stroke, bleeding, and pulmonary edema, which can lead to
As dense breast tissue notification laws expand and draw media coverage, the role of molecular breast imaging (MBI) also is drawing more attention in breast cancer detection. New research looking at everything from lesion detection rates to specificity and dose reductions is helping breast imagers define MBI’s place in the rotation of adjunct breast imaging
Utilizing prostatic artery embolization (PAE) to shrink the prostate without surgery can provide long-term relief to men with benign prostatic hyperplasia (BPH), a common condition that causes annoying symptoms such as frequent trips to the bathroom. Results from a study of nearly 500 men receiving PAE treatment were presented at SIR’s annual meeting. Researchers reported
Nonscreened Patients With Breast Cancer Need More Treatment Than Screened Patients Screening women aged 40 to 49 for breast cancer has additional benefits beyond the proven decrease in mortality rate, according to researchers at Case Western Reserve University. Patients screened with mammography are statistically less likely to undergo chemotherapy, avoiding the associated toxic morbidities. Screening
PET is a promising tool for determining which severely brain-damaged individuals in a vegetative state could potentially recover consciousness, according to new research published in The Lancet. It’s the first time that researchers have tested the diagnostic accuracy of functional brain imaging techniques in clinical practice. “Our findings suggest that PET imaging can reveal cognitive
Quantitative plaque analysis using cardiac CT angiography (CCTA) provides an accurate assessment of arterial plaque and could dramatically impact the management of patients with diabetes who face a high risk of heart attacks and other cardiovascular events, according to new research. Plaque that forms in the arterial walls can restrict blood flow and, in some
Liver cancer survival rates could be improved if more people with cirrhosis are screened for tumors using ultrasound scans and blood tests, according to a review published in PLOS Medicine by physicians at UT Southwestern Medical Center in Dallas. The meta-analysis of 47 studies involving more than 15,000 patients found that the three-year survival rate
