CT scans are often used to find cancer, bone fractures, internal bleeding, blood clots, and injuries to the spine and brain. An MRI shows certain diseases that a CT scan can’t. For instance, uterine, prostate, and certainliver cancersare hard to see on a CT scan. Also, an MRI is u...

A previous meta-analysis of 26 trials of ACT after surgery in NSCLC demonstrated a ∼4% absolute survival benefit at 5 years7, meaning a significant subset of patients enrolled in these trials were cured by surgery and thus may not benefit from adjuvant therapy. In our cohort, although ...

Improving CT scan resultsDescribed are methods, systems and computer program products for correcting contrast levels in medical images of the vascular system. One method includes identifying an overall reference contrast level. The method determines, for each image position representing a position in the...
it facilitates a single imaging session without the need for a second CT or subsequent scan. Secondly, it enables voxelwise alignment, providing true spatial multiplexing. This capability is crucial for understanding the spatial heterogeneity of tumours, as the multiplexed image can simultaneously high...
In CT scan coding, modifiers are used to indicate specific circumstances that affect the way the procedure is performed, or the circumstances under which the service is provided. For provider reference purposes, we are sharing commonly used modifiers for CT scans (along with their meaning): ...
meaning that every part of the image is in focus. What’s more, no stitching of multiple images is required, eliminating the errors that result from circular scanners. Instead, the sample is rotated in a helical formation with the integrated algorithms turning the data into a...
A CT scan uses what’s called “ionizing” radiation. It’s powerful enough to pass through your body to create clear images on a computer. This type of radiation could raise your chances ofcancerat some point in the future. But it’s important to remember that ionizing radiation is around...
