Post-Treatment qSPECT/CT Dosimetry in Radiopharmaceutical Therapy

Enhancing Precision and Safety in Cancer Care

At United Theranostics, our commitment to personalized, effective cancer treatment extends beyond therapy administration. Post-treatment quantitative SPECT/CT (qSPECT/CT) dosimetry is an advanced imaging and analytics process that measures the actual radiation dose delivered to tumors and healthy tissues after radiopharmaceutical therapy. This approach ensures precise, individualized care for every patient.

What is qSPECT/CT Dosimetry?

Quantitative SPECT/CT (qSPECT/CT): A hybrid imaging technique that combines functional (SPECT) and anatomical (CT) scans to provide three-dimensional, quantitative maps of radiopharmaceutical distribution within the body.
Dosimetry: The calculation and assessment of the radiation dose absorbed by tissues, enabling clinicians to tailor future treatments and optimize safety and effectiveness.

Why is Post-Treatment Dosimetry Important?

Personalized Assessment: Measures the actual dose received by tumors and critical organs, rather than relying solely on standardized dosing.
Optimized Outcomes: Helps guide adjustments to future therapy cycles, maximizing tumor control while minimizing side effects.
Safety Monitoring: Identifies patients at risk of higher-than-expected exposure to sensitive tissues (e.g., kidneys, bone marrow).
Treatment Validation: Confirms that the radiopharmaceutical has effectively targeted the intended cancer sites.

How the Process Works

Radiopharmaceutical Therapy: Patient receives a targeted radiopharmaceutical treatment (e.g., Lutetium-177, Iodine-131, Radium-223).
qSPECT/CT Imaging: After therapy, a qSPECT/CT scan is performed to visualize and measure the distribution of the radiopharmaceutical.
Dosimetric Analysis: Advanced software calculates the absorbed radiation dose in tumors and normal tissues.
Clinical Review: Results are reviewed by the clinical team to inform future treatment planning and patient counseling.

Who Benefits from Post-Treatment Dosimetry?

Patients receiving radiopharmaceutical therapies for metastatic prostate cancer, neuroendocrine tumors, thyroid cancer, and other malignancies.
Individuals requiring personalized treatment adaptation based on their unique response to therapy.

Frequently Asked Questions (FAQ)

B
C

What is the purpose of post-treatment qSPECT/CT dosimetry?

It provides a precise measurement of the radiation dose delivered to both tumors and healthy tissues, allowing your care team to tailor future treatments for optimal safety and effectiveness.
B
C

How is the qSPECT/CT scan performed?

The scan is non-invasive and typically performed within hours to days after radiopharmaceutical therapy. You will lie on a scanning table while the SPECT/CT camera acquires detailed images of your body.
B
C

Is the scan safe?

Yes. The procedure is non-invasive and uses the radiopharmaceutical already administered as part of your therapy. No additional radioactive material is required.
B
C

Will I feel any discomfort during the scan?

Most patients experience no discomfort. The process is similar to standard imaging scans and typically takes 30–60 minutes.
B
C

How are the results used?

Your clinical team uses the dosimetry results to confirm that your treatment is on target and to make any necessary adjustments to future therapy cycles for maximum benefit and safety.
B
C

Does every patient need post-treatment dosimetry?

While highly recommended for many patients receiving radiopharmaceutical therapy, the need for dosimetry is determined by your care team based on your diagnosis, therapy type, and clinical goals.
