PET/CT (Positron Emission Tomography/Computed Tomography)

PET/CT combines two powerful imaging techniques in a single scan. PET reveals how tissues and organs are functioning at the molecular level, while CT provides detailed anatomical images. This combination helps us:

Detect cancer early and accurately
Pinpoint the exact location and extent of disease
Monitor how well treatments are working

PET/CT is especially helpful for complex cancers like metastatic prostate cancer, neuroendocrine cancer, and thyroid cancer.

CT (Computed Tomography)

CT uses X-rays and advanced computer technology to create highly detailed cross-sectional images of the body. These scans allow physicians to examine internal organs, bones, soft tissues, and blood vessels with exceptional clarity.

CT scans are:

Fast, non-invasive, and painless
Excellent for visualizing tumors, lymph nodes, and internal organs
Helpful for detecting the size, shape, and location of abnormalities
Frequently used to guide biopsies and minimally invasive procedures
Valuable for monitoring how cancers respond to treatment over time

CT imaging plays a critical role in cancer diagnosis, staging, treatment planning, and ongoing disease management. At United Theranostics, CT is often used alongside advanced molecular imaging technologies to provide a more complete picture of a patient’s condition and support personalized care decisions.

SPECT/CT (Single Photon Emission Computed Tomography/Computed Tomography)

SPECT/CT combines functional imaging from SPECT with the detailed anatomical imaging of CT in a single scan. By merging these technologies, physicians can better understand both how tissues are functioning and where abnormalities are located within the body.

This advanced hybrid imaging allows us to:

Visualize blood flow, metabolic activity, and cellular function
Detect abnormalities that may not appear on conventional imaging alone
Improve localization of tumors and areas of disease activity
Support more precise treatment planning and therapy monitoring
Evaluate how targeted radiopharmaceutical therapies are working over time

SPECT/CT plays an important role in nuclear medicine and theranostics, particularly for patients receiving targeted cancer therapies. By combining functional and anatomical information, SPECT/CT helps physicians make more informed decisions and deliver highly personalized care.

Frequently Asked Questions (FAQ)

What is the difference between PET/CT, CT, and SPECT/CT?

PET/CT and SPECT/CT both combine functional (how your body is working) and anatomical (what your body looks like) imaging. PET/CT uses a different type of tracer than SPECT/CT, which can be better for certain cancers. CT alone provides a detailed picture of your body’s structure without the functional information.

Are these imaging procedures safe?

Yes. All scans use low doses of radiation and are performed by experienced technologists. Your doctor will only order these scans when the benefits outweigh any risks.

How should I prepare for my scan?

Preparation depends on the specific scan. You may be asked to avoid eating or drinking for a few hours beforehand. Our team will provide detailed instructions before your appointment.

Will I feel anything during the scan?

The scans themselves are painless. You may receive a small injection of a tracer for PET/CT or SPECT/CT, but most patients experience minimal discomfort.

How long does the scan take?

Most scans take between 30 and 90 minutes, depending on the type of imaging and your specific needs.

When will I get my results?

Results are typically available within a few days. Your doctor will review the images and discuss the findings with you.

Do you accept insurance?

Yes. We work with most major insurance providers and offer assistance with insurance verification and financial programs if needed.
