The hand and wrist are intricate structures composed of bones, joints, tendons, ligaments, and nerves. They perform crucial functions in our daily lives, enabling us to grasp, manipulate objects, and engage in various activities. However, due to their complexity and vulnerability to injuries and diseases, accurate diagnosis and proper treatment are essential. In the field of medicine, imaging plays a vital role in assessing and diagnosing hand and wrist conditions, providing valuable insights into the underlying issues and guiding appropriate management strategies.

Traditionally, the examination of the hand and wrist involved physical evaluation, patient history, and a series of clinical tests. While these methods are still valuable, medical imaging has revolutionized the diagnostic process, allowing healthcare professionals to visualize the internal structures of the hand and wrist in great detail. Several imaging modalities are employed in the evaluation of hand and wrist disorders, each offering unique advantages depending on the clinical scenario (Figure 1).

X-ray imaging, or radiography, is often the first-line imaging modality used to evaluate hand and wrist conditions. X-rays provide a detailed view of the bones and joints, aiding in the detection of fractures, dislocations, joint abnormalities, and degenerative changes such as osteoarthritis. They are quick, readily available, and relatively low-cost, making them an invaluable tool in the initial assessment of hand and wrist injuries [1].

In cases where soft tissue structures such as tendons, ligaments, and nerves are of concern, ultrasound imaging can be highly beneficial. Ultrasound utilizes high-frequency sound waves to create real-time images of the hand and wrist. It is particularly useful in assessing tendon injuries, detecting abnormalities in ligaments, identifying fluid collections, and evaluating nerve compression syndromes like carpal tunnel syndrome. Ultrasound is non-invasive, portable, and allows dynamic assessment of structures during movement, making it an excellent tool for real-time diagnosis and guided interventions.

Magnetic Resonance Imaging (MRI) is another valuable imaging modality for the evaluation of hand and wrist conditions. MRI utilizes a powerful magnetic field and radio waves to generate detailed crosssectional images of the hand and wrist. It provides excellent visualization of soft tissues, including tendons, ligaments, cartilage, and nerves. MRI is particularly useful in assessing complex injuries, detecting subtle abnormalities, and identifying conditions such as tendonitis, ligament tears, ganglion cysts, and tumors. Additionally, MRI can assess the extent of joint damage in chronic conditions like rheumatoid arthritis [2].

Computed Tomography (CT) imaging may be employed in specific cases where a more detailed assessment of bony structures is required. CT scans provide highly detailed 3D images of the bones, making them useful for evaluating fractures, bony abnormalities, and complex fractures that require surgical planning. CT imaging is particularly valuable when assessing the alignment and anatomical relationships of bones in complex fractures or cases involving joint replacements.

In some instances, a contrast-enhanced imaging study, such as Magnetic Resonance Arthrography (MRA) or Computed Tomography Arthrography (CTA), may be performed to enhance visualization of specific structures. These techniques involve the injection of a contrast agent into the joint space, enabling better assessment of structures like the triangular fibrocartilage complex (TFCC) in the wrist or intraarticular ligaments in the hand. This aids in the diagnosis of ligament tears, cartilage injuries, and other pathologies.

In conclusion, imaging of the hand and wrist has become an indispensable diagnostic tool in the field of medicine. X-rays, ultrasound, MRI, and CT scans provide healthcare professionals with valuable information about the bones, joints, tendons, ligaments, and nerves in the hand and wrist by combining clinical evaluations with imaging findings.
