Nuclear Medicine

Department of Nuclear Medicine & Molecular Imaging (PET CT)


Started in 1996, this department was one of the important milestones, in the development of Ruby Hall Clinic, as it was the first Hospital owned Nuclear Medicine Department, outside Bombay, in state of the Maharashtra. Nuclear Medicine is science of using Nuclear energy for peaceful purpose. Radiopharmaceuticals are molecules or chemicals that are attached to a small amount of radioactive isotope that once administered to the patient are able to specifically localize within organs and/or organ systems in health and disease. The imaging is done with highly sophisticated equipment known as GAMMA CAMERA SYSTEM. RUBY HALL CLINIC has, upgraded its imaging system three times since the inception of the department, and recently has a state of the art, Dual head Gamma camera system. Services /Tests/ Treatments The Department of Nuclear Medicine provides the following services:

Diagnostic Tests

  • PET-CT
  • Whole Body PET CT Scan
  • Cardiac PET for Myocardial Viability
  • Brain PET for intractable epilepsy evaluation

Gamma Scans

  • Thyroid: Hyperthyroidism, Goiter or Cancer
  • Bone: Bone cancer spread or identifying causes of pain
  • Kidneys: Obstruction from stones or congenital, Renal Failure Pediatric
  • Imaging: Ureter Obstruction, Gastric Emptying and Reflux, Oncology
  • Heart: Ischemia, Heart Muscle Viability, Ejection Fraction
  • Liver/Gall Bladder: Abdominal Pain, Function of liver, gallbladder
  • Lungs: Blood flow obstruction and/or airway obstruction
  • Parathyroid: High Calcium Production
  • Stomach: Gastric Motility, Reflux
  • Brain: Epilepsy, Tumors
  • Breast Cancer
  • Cancer: All Organs
  • Infection and Inflammation: Osteomyelitis, Abscess

Therapy Treatments

  • Hyperthyroidism, Toxic nodular Goitres
  • Thyroid Cancer – Papillary, Follicular, Medullary types
  • Bone: Pain Palliation in Cancer Patients
  • Liver Cancers (SIR micro spheres)

Technology / Equipments


Ruby Hall Clinic has acquired country’s first “Time of Flight” PET CT scanning machine, in 2008. Fast and accurate scanning with least radiation exposure, are features of the TOF PET scan at Ruby Hall Clinic. In addition, the whole body PET CT scan is finished just in 12 min. It’s an OPEN PET CT gantry, which means there is no CLAUSTROPHOBIA (Fear of closed places) as there is no long tunnel in which the patient has to go for scanning. The scan appointments are given at 8:00 am onwards from Mon to Saturday except Holidays.

Gamma Camera

Ruby Hall Clinic has also recently upgraded its Gamma camera system, by a latest Dual Head Gamma camera system. This enables a very high quality functional imaging, in half the time for most of the procedures, as there are two Camera heads scanning the patient simultaneously.

High Dose Therapy Facility

The High Dose therapy facility of our hospital is for treatment of cancers of Thyroid. It is a unique facility wherein a patient with life support also can be treated. The same facility is also used for treatment of pain palliation, SIR treatment for Liver malignancies, MIBG therapies for Neuroblastoma, Pheochromocytoma and Medullary types of thyroid cancers.

What is Nuclear Medicine? Nuclear Medicine is a medical specialty in which the diagnosis and treatment of human diseases are made by the use of a small amount of radioactive tracers. After administration of the tracer, images of the organ of interest in the patient’s body are obtained with a gamma camera that show the localization of the tracer in the organ, and physicians interpret them for the diagnosis of disease. Certain diseases are treated with high energy radiotracers in nuclear medicine based on the concept that high dose radiation kills cells.

How is a nuclear medicine study performed?

The patient is given intravenously, for some studies orally or by inhalation, a small dosage of a radiotracer specific for an organ under study. Some studies require that the patient exercise or receive a drug that dilates the arteries in the heart. The tracer localizes in the organ and emits gamma radiations that are detected by a special camera to form an image of the organ. Imaging of the organ is performed immediately, hours or days after administration of the tracer, depending on the type of study. The duration of imaging itself ranges from 15 to 120 minutes for different studies. Most tests require the patient to lie down on a bed, while others require the patient to sit. Some tests require taking many short pictures of the organ serially followed by one long picture at the end. Nuclear physicians interpret the images and can see any abnormality in the image either as a ‘hot’ area with increased localization of the tracer or a cold spot with decreased localization of the tracer, depending on the property of the tracer.

How is the tracer administered?

The tracer is administered most commonly by injection through the vein, and for some tests orally or by inhalation.

How long does a nuclear medicine test take?

It depends on the type of test. Since the localization of the radiotracer varies with the physiological behavior of the organ and the characteristics of the tracer, the time for optimal localization varies from organ to organ. Sometimes two tests are needed for some disease entities such as with cardiac studies. For example, a lung scan needs only half an hour, a heart study may take 2 – 3 hours, and yet other tests may takes 24-48 hours to complete.

Does a patient need to make specific preparations for a study?

Some tests require minimal or no preparation, (e.g. bone, brain, kidneys and lungs), whereas others require specific preparations such as fasting for 2-4hours and no Beta blocker medicines for 24 hours (cardiac studies). During scheduling of the test, the patient will be instructed for the specific preparation.

Are there any side effects from these studies?

Because the administered radioactive dosages contain only a minimal amount of the carrier drug, no significant adverse or allergic reactions from the drug are commonly encountered. A patient receives a certain amount of radiation dose from nuclear medicine studies which is comparable to a diagnostic X ray.

What are the benefits of nuclear medicine?

Nuclear medicine tests are very sensitive and can detect some diseases at early stages. Unlike MRI and CT studies that give only structural information, nuclear medicine tests provide information about the physiological or functional status and viability of different organs and tissues.

How does a patient make an appointment?

A primary physician or specialist can make a patient referral to the department or a patient make the appointment directly by calling, 020-6645 5265, 020-3052 3000. OR 020-6645 5100 (60 Lines)
