Nuclear Medicine & PET-CT

Dual Head Gamma Camera (Millennium MG)

● Radiopharmaceuticals are organ specific chemical compounds combined with radionuclides.

● These radiopharmaceuticals, once administered to the patient, localize to specific organs or cellular receptors which allows us to image the extent of a disease-process in the body, based on the cellular function (Physiology), rather than relying on physical changes in the tissue anatomy.

Dual Head Gamma Camera (Millennium MG)

Application

Functional/Physiological imaging of various Organs/Organ systems

BONE SCAN

● Highly sensitive● Surveys entire body in

a single study● Diagnoses the lesion

earlier than radiograph

EARLYDiagnosis of bone secondaries in a cancer patient

BONE SCAN

THYROID SCAN

Provides the Uptake Function of Thyroid Gland

Detectes Nonfunctioning Nodules (30% of Which Could be Cancerous )

Differentiates Hyperthyroidism Causes

Thyroid Scan Graves’ Disease

Curable with Radioiodine Therapy

● Patient Presented with Thyroid Swelling

● Thyroid Scan Shows Nonfuntioning Nodule

● Biopsy Revealed Thyroid Cancer

● Complete Cure for Thyroid Cancer at early stage (Papillary & Follicular Varieties) is Possible with Surgical Removal of Thyroid Gland with

Neck Lymphnode Dissection

Followed By High Dose Radioiodine Therapy
