What is upper extremity imaging?

(Shoulder, Wrist, Hand, & Finger) A CT of the Upper Extremity is a noninvasive medical scan that uses special equipment to produce detailed pictures of the soft tissues, joints and bones of your shoulder, arm or hand. These CT images are far more detailed than those obtained from conventional x-rays.

Why is MRI better than other modalities in scanning extremities?

MRI does not use ionizing radiation (X-rays). Detailed MR images allow physicians to better evaluate various parts of the body and determine the presence of certain diseases that may not be assessed adequately with other imaging methods such as X-ray, ultrasound or computed tomography (also called CT or CAT scanning).

What does an MRI show in arm?

Magnetic resonance imaging (MRI) uses a magnetic field, radio waves and a computer to create detailed image slices (cross sections) of the various parts of your arm: upper arm, elbow, lower arm, wrist, hand, and fingers, as well as the different types of tissue: cartilage, ligaments, tendons or the meniscus (shock …

What does a CT scan of the hand show?

CT scan of the extremities can provide more detailed information about bone and soft tissue structures than standard X-rays of the extremities. Therefore, this can provide more information related to injuries, infections and masses, and can be used to evaluate patients with pain, swelling, or after trauma.

What can an MRI show that a CT scan Cannot?

Where MRI really excels is showing certain diseases that a CT scan cannot detect. Some cancers, such as prostate cancer, uterine cancer, and certain liver cancers, are pretty much invisible or very hard to detect on a CT scan. Metastases to the bone and brain also show up better on an MRI.

Which is the best MRI for upper extremity joints?

Clinical MRI is done on units ranging between 0.2 T and 3 T. Low-field imaging tends to be below 0.5 T. Between 0.5 T and 1.0 T is considered midfield imaging. High-field imaging is above 1.0 T. High-field imaging at 1.0 T and above is preferred for upper extremity joint imaging.

How is the wrist positioned in an MRI?

Technical Considerations for MRI of Upper Extremity Joints. The wrist can be positioned in several ways, including with the patient supine and the arm at the side, in the superman position with the patient prone, or in the lateral decubitus position with the arm extended above the patient’s head ( Figs. 2.5 and 2.6 ).
