Description
Single Photon Emission Computed Tomography (SPECT) helps diagnose heart disease, brain disorders, and bone conditions; in China, it typically costs ¥200–¥500, with ChinaMedicalHub assisting hospital booking and interpreter support.
Main Uses
SPECT is primarily used for: 1. Evaluating blood flow to the heart and detecting coronary artery disease, 2. Assessing brain function and diagnosing conditions like Alzheimer's, Parkinson's, and epilepsy, 3. Identifying bone disorders, including fractures, infections, and tumors, 4. Investigating gastrointestinal, renal, and endocrine system functions, 5. Guiding treatment planning and monitoring response to therapy in various cancers.
Normal Range
The normal range for Single Photon Emission Computed Tomography (SPECT) varies based on the specific organ or system being examined and the radiotracer used. Generally, a normal SPECT scan shows uniform distribution of the radiotracer with no areas of significant increase or decrease in uptake. For example, in a cardiac SPECT, the myocardial perfusion should be homogeneous without any defects.
Low Values - Possible Causes
Decreased uptake in SPECT can be caused by: 1. Reduced blood flow to the area, 2. Tissue death or necrosis, 3. Previous surgical removal of tissue, 4. Certain medications that affect blood flow, 5. Blockages in arteries leading to the organ.
High Values - Possible Causes
Increased uptake in SPECT may indicate: 1. Inflammation or infection, 2. Tumors or cancerous growths, 3. Hyperactivity of an organ, such as hyperthyroidism in thyroid scans, 4. Areas of high metabolic activity, 5. Healing fractures or bone repair processes.
