Three-Phase Bone Scan in Chennai
What is this study?
A Three-Phase Bone Scan is a nuclear medicine imaging procedure used to evaluate blood flow, soft tissue, and bone involvement in conditions such as complex regional pain syndrome (CRPS), also known as reflex sympathetic dystrophy (RSD), and osteomyelitis.
What is the need for the study?
The Three-Phase Bone Scan is needed to:
- Assess blood flow to the affected area and detect abnormalities in soft tissues and bones.
- Diagnose and monitor the progression of complex regional pain syndrome (CRPS) and osteomyelitis.
- Guide treatment decisions and monitor response to therapy.
How do I prepare?
Preparation for a Three-Phase Bone Scan is similar to an MDP Bone Scan and typically involves:
- Drinking plenty of fluids before the scan.
- Avoiding calcium supplements and medications containing calcium.
- Informing your healthcare provider about any recent surgeries, fractures, or other medical conditions.
How is this scan performed?
During a Three-Phase Bone Scan:
- Blood flow phase: You will receive an injection of a radioactive tracer, usually technetium-99m (Tc-99m) labeled MDP, into a vein in your arm. Images are taken immediately to assess blood flow to the affected area.
- Soft tissue phase: Images are taken a few minutes later to assess soft tissue involvement.
- Delayed bone phase: Images are taken a few hours later to assess bone uptake of the tracer.
What should I do after the scan?
After the Three-Phase Bone Scan:
- You can resume normal activities.
- Attend any follow-up appointments to discuss the results of the scan and further management, if necessary.
Are there any risks in the study?
Three-Phase Bone Scans are generally considered safe, with minimal risk associated with the radioactive tracer. The amount of radiation exposure is low and unlikely to cause harm. However, pregnant or breastfeeding women should inform their healthcare provider before the scan. Allergic reactions to the tracer are rare but possible.
Always follow the instructions provided by your healthcare provider and inform them of any concerns or allergies before undergoing nuclear medicine procedures.
