Summary
A 42-year-old man experienced ulnar-sided wrist pain. Advanced imaging confirmed ulnar impaction syndrome, highlighting bone marrow edema in the lunate bone.
Area of Science:
- Orthopedics
- Radiology
- Musculoskeletal Imaging
Background:
- Ulnar-sided wrist pain is a common complaint.
- Accurate diagnosis is crucial for effective treatment.
Observation:
- A 42-year-old male presented with ulnar-sided wrist pain.
- Magnetic Resonance (MR) imaging revealed bone marrow edema in the lunate bone.
- MRI and arthrography diagnosed ulnocarpal impaction syndrome.
Findings:
- Bone scintigraphy indicated increased radiotracer uptake in the affected wrist.
- SPECT/CT imaging with 2D and 3D reconstructions precisely localized abnormal accumulation to the ulnar aspect of the lunate bone.
Implications:
- SPECT/CT provides detailed anatomical and functional information for diagnosing wrist conditions.
- This case highlights the utility of advanced imaging in identifying the precise location of pathology in ulnar impaction syndrome.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
01:27Imaging Studies III: Computed Tomography
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
