PET/CT Technology and The Benefits

Better Than PET Alone

PET / CT is one of the most discussed medical imaging innovations today. Oncologists, and other related cancer specialists also cardiologists, neurologists, and patients are all interested in this combination. The CT provides fine anatomical resolution with unique metabolic information provided by PET imaging. The fusion of these two images into a combined, single review is a result that is greater than the sum of its parts. Fusion data before surgery helps assess the size, shape and location of a tumor.

Clinical experience clearly shows that the PET / CT image provides valuable information, primarily in differentiating malignancies amongst closely packed tissue. The head and neck in particular have many anatomical structures confined within a very small space or a central lung tumor with a collapsed lung or atelectasis around it. In these types of cases, PET / CT gives a more accurate localization for radiation therapy planning and monitoring in response to treatment over time as well as aiding in planning further treatment or surgery.

Recent studies prove that in comparison with standard PET, the use of combined PET / CT
improves diagnostic accuracy and reduces the number of equivocal imaging findings.


Answers to frequently asked questions about PET/CT
What PET/CT patients can expect.


Clinical relevance of PET / CT:

  • Earlier diagnosis and lesion detection
  • Persistent high accuracy in image interpretation
  • Significant decrease in the number of equivocal findings
  • Precise localization for improved biopsy sampling
  • Accurate assessment of patient responses to chemotherapy and radiation therapy Overall, PET / CT helps improve the clinical efficacy of PET, expanding the diagnostic capabilities of physicians, and improves patient outcome as well as their comfort and convenience with less imaging time on the table.
