Sex-Specific CAC Thresholds May Predict Obstructive CAD, Study Finds
Understanding CAC and Obstructive CAD Coronary artery calcium (CAC) scoring is a widely used, noninvasive test that measures calcified plaque in the coronary arteries. While CAC can help assess a patient’s risk of heart disease in general, its role in predicting obstructive coronary artery disease (CAD) among those with chest pain or other symptoms is…

New ultrasound technology cuts false positives in breast imaging
Groundbreaking approach helps differentiate fluid from solid masses A new ultrasound technology developed at Johns Hopkins is changing the way breast imaging is interpreted by accurately distinguishing fluid-filled cysts from solid masses. This capability addresses a long-standing challenge in breast ultrasound, where dense breast tissue can obscure or mimic suspicious findings, often leading to additional…

Fluorescent Dye Helps Highlight Lung Nodules: What Patients Should Know
Understanding Lung Nodules and Why They Matter Lung nodules are small, round or oval growths in the lungs. They often appear on imaging tests done for unrelated reasons and can range from benign to potentially cancerous. Because nodules are typically very small, doctors rely on imaging techniques and, in some cases, special dyes or contrast…

Dye Illuminates Lung Nodules for Early Cancer Detection
Understanding Lung Nodules and the Challenge of Early Detection Lung nodules are small, round growths in the lungs that show up on imaging tests like CT scans. While most nodules are benign, some can indicate early stages of lung cancer. Because nodules are often tiny—sometimes only a few millimeters across—spotting them early can be difficult.…

Could low-dose CT scans replace chest X-rays for early lung cancer detection? MEDLEY study underway
New study aims to improve early detection of lung cancer A major new study, MEDLEY, is underway with recruitment in several UK cities. The project, funded by the National Institute for Health Research (NIHR), seeks to determine whether low-dose computed tomography (CT) scans can improve the early detection of lung cancers compared with the traditional…

Fatty Liver Surge (+15%): Tests, Monitoring, and the Role of AI
What is MASLD and why are cases rising? Global health experts are sounding the alarm over a sharp rise in fatty liver disease, now often referred to as MASLD (Metabolic dysfunction-associated steatotic liver disease). Recent estimates place the condition in roughly 38% of the adult population worldwide, representing a 15% increase compared with two decades…
