CT scan vs. MRI quick comparison of differences Picture: A medical technician prepares a patient for an MRI to check for a possible brain tumor CT scansutilizeX-raysto produce images of the inside of the body whileMRI(magnetic resonance imaging) uses powerful magnetic fields and radiofrequency ...
Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, compared to...

The CT scanner looks like a large donut with a narrow table in the middle. Unlike MRI, in which the patient would be placed inside the tunnel of the scanner, when undergoing a CT scan, the patient rarely experiences claustrophobiabecause of the openness of the doughnut shape of the scanner...
When to Consider Each Imaging Option: MRI, CT Scan or X-ray X-ray for Osteoarthritis: Ideal for Initial Diagnosis: X-rays are often sufficient for diagnosing osteoarthritis, characterized by morning stiffness that improves after movement. Cost-effective: Compared to MRI and CT scans, X-rays are...
A CT scan is better than an MRI for the imaging of calcified tissues, like bones. CT scans produce excellent detail used to diagnose osteoarthritis and fractures. Also, patients with metal or certain medical implants cannot undergo MRIs due to the magnetic field pulse. However, CT scans can ...
Apart from those limitations, MRI scans are safe, painless and have no ill effects on the body. What Are CT Scans? Computer tomography scans combine a series of X-ray images taken at a variety of angles to produce a more detailed picture than a regular X-ray. CT scans are preferred ...
PET检查，大医院核医学科可以做，是目前诊断肿瘤最灵敏的检查了，而且是全身性的，要几千块钱。它是要把显像剂从静脉注入人体，然后在仪器下显像，早期的没有发生形态学改变的病灶也能够显示，这是CT和MRI无法做到的。还有一种更昂贵的，叫PET-CT，是把PET和CT图像结合取来，取两者优点，比PET图像...
A series of X-ray emitters and detectors are in the tunnel's center (gantry). These are far less claustrophobic and loud compared to older systems. The radiographer will conduct the CT scan from a radiation-safe control room adjacent to the scanning room. ...
