~3 per 10,000 per year (wrist and hand) [5] A ganglion cyst is a fluid-filled bump associated with a joint or tendon sheath . [ 3 ] It most often occurs at the back of the wrist , followed by the front of the wrist.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
PET images can be viewed in comparison to computed tomography scans to determine an anatomic correlate. Modern scanners may integrate PET, allowing PET-CT, or PET-MRI to optimize the image reconstruction involved with positron imaging. This is performed on the same equipment without physically moving the patient off of the gantry.
Front X-ray of right knee of an adolescent (epiphyseal plates are open): arrows point to avascular necrosis and developing osteochondritis dissecans in the outer medial condyle of femur. In the early stages, bone scintigraphy and MRI are the preferred diagnostic tools. [18] [19] X-ray images of avascular necrosis in the early stages usually ...
[30] [24] Active surveillance includes monitoring with MRI in intervals (e.g., every 6 months) to ensure the delay in treatment does not pose a potential harm. [24] This should be carefully weighed against the potential for over treatment. Vimseltinib (Romvimza) was approved for medical use in the United States in February 2025. [31]
Arthroscopic image of a central triangular fibrocartilage complex (TFCC) tear. X-ray: X-rays of the wrist are made in two directions: posterior-anterior (PA) and lateral. Radiographs are useful to diagnose or rule out possible bone fractures, a positive ulnar variance or osteoarthritis. The TFCC is not visible on an X-ray, regardless of its ...
SLAC wrist is the most common type of post-traumatic wrist osteoarthritis [1] and is often the result of an undiagnosed or untreated scapholunate ligament rupture. [2] The condition follows a predictable pattern of development, which was first described by H. Kirk Watson, M.D. and Frederick L. Ballet, M.D. in 1984.
Kienböck's disease is a disorder of the wrist.It is named for Dr. Robert Kienböck, a radiologist in Vienna, Austria who described osteomalacia of the lunate in 1910. [1]It is breakdown of the lunate bone, a carpal bone in the wrist that articulates with the radius in the forearm.
