The PET-CT scanner at Carcinova Cancer Hospital combines two state-of-the-art imaging modalities. PET (Positron Emission Tomography) provides highly sensitive information regarding cellular glucose metabolism, helping to evaluate the function and malignant potential of lesions. Meanwhile, CT (Computed Tomography) offers detailed anatomical information about the location, size, and shape of various lesions. However, CT alone cannot differentiate between benign and malignant lesions with the same accuracy as PET. The combined PET-CT scanner merges PET and CT images, enabling physicians to pinpoint malignancies with greater precision and ultimately stage the patient more accurately.
Positron emission tomography (PET) uses small amounts of radioactive materials called radiotracers or radiopharmaceuticals, along with a special camera and computer, to evaluate organ and tissue functions. By identifying changes at the cellular level, PET may detect the early onset of disease before other imaging tests can.
Nuclear medicine involves the use of small amounts of radioactive material called radiotracers. Doctors use nuclear medicine to diagnose, evaluate, and treat various diseases such as cancer, heart disease, gastrointestinal, endocrine, or neurological disorders. Nuclear medicine exams pinpoint molecular activity, providing the potential to detect disease in its earliest stages and to monitor whether you are responding to treatment.
PET, being a functional imaging technique, is superior to conventional anatomical imaging in the diagnosis, staging, restaging, and monitoring of various cancers. The appropriate use of PET can significantly impact the management of a patient's care, leading to more accurate treatment decisions.
PET is highly sensitive in determining the full extent of disease, especially in cancer patients. Detecting metastatic disease helps physicians and patients make more informed decisions regarding treatment and care management.
PET is considered the most accurate diagnostic tool for differentiating tumor recurrences from radiation necrosis or post-surgical changes. This allows for a more rational treatment plan to be developed, improving patient outcomes.
