PET/CT in Oncology

Vocabulary flashcards based on the key concepts covered in the PET/CT in Oncology lecture.

CT

Computed Tomography, an imaging technique to create detailed images of the body.

PET

Positron Emission Tomography, an imaging test that helps reveal metabolic or biochemical activity.

FDG

Fluorodeoxyglucose, a radiotracer used in PET scans to visualize metabolic processes.

Tumor Characterization

The process of identifying and defining the characteristics of a tumor through imaging.

Advantages of PET/CT

Includes enhanced lesion detection and better lesion characterization.

Imaging Protocol

The specific steps and guidelines followed for conducting imaging exams.

Lesion Detection

Identifying abnormal tissue masses that may indicate disease.

Metabolic Rates

The rate at which the body consumes energy and converts it into usable forms.

PET/CT Applications

Used for diagnosing conditions like epilepsy, tumors, and dementia.

Diagnosis and Staging

The process of identifying the presence and extent of cancer.

National Oncologic PET Registry

A database tracking PET scan results and their impact on cancer treatment.

False Positive Findings

Test results indicating a condition that is not actually present.

False Negative Findings

Test results indicating no condition when there is one.

Clinical Impact of PET/CT

Improves diagnostic accuracy and helps avoid unnecessary treatments.

Enhanced Detection

The ability of PET/CT to identify abnormalities not seen on standard imaging.

Granulomatous Disease

Conditions characterized by the formation of granulomas, often misinterpreted in imaging.

Standard CT vs PET/CT

CT provides initial imaging, but PET/CT offers additional functional information.

PET Tracer Administration

Involves injecting a radioactive glucose analog before imaging.

Cancer Management Plan

The strategy developed for treating a patient's cancer.

Occult Cancer Detection

The identification of cancer that cannot be detected through conventional imaging.

Therapy Response Evaluation

Assessing how well a cancer treatment is working through imaging.
