Launched Nuclear Medicine Department
Gamma Scans is a company runs professionally and has been setting up the Gamma Cameras in North India having centres at New Delhi, now at Panipat & another one coming up in Chandigarh. It is headed by Dr. Anupam Gauba MD (Nuclear Medicine) from TATA Memorial Cancer Hospital, Mumbai
Gamma Scans feel privileged to announce the inception of its Nuclear Medicine Department with Gamma Camera at Lala Harbhagwan Dass Memorial & Dr. Prem Hospital Pvt. Ltd., Panipat from Intermedical, Germany. This Gamma Camera boasts of its Highest Sensitivity, which reduces the radiation burden to the patient. In most of the scans the radiation burden to the patient is less than or equal to that of a Conventional X-ray Radiation.
Q: What is Nuclear Medicine?
Nuclear Medicine is the Branch of medicine that utilizes radio-isotopes for the diagnosis and treatment of diseases.
Principle of Nuclear Medicine
It uses the principle that a certain radio-pharmaceutical (tracer) will at a certain point in time have a preferential uptake by a particular
organ or tissue.
This uptake is then imaged by the use of detector mounted in Gamma Cameras.
Advantages of Gamma Camera over MRI/CT scan
Since it’s a physiological imaging Gamma Camera has an inherent property to diagnose the disease or clinical problem much earlier.
Since it’s a dynamic imaging, tests can be designed according to the patient’s peculiar clinical indication.
Unlike the anatomical imaging Gamma Camera can be used to evaluate the functional reserve of an organ rather than just evaluating the
present state of function.
Dynamic imaging also helps in acquiring the data in MPEG format, unlike a JPEG format acquired in anatomical imaging; in simple words
it makes a movie of a functioning organ rather than just acquiring a still photography.
Advantages of Nuclear Medicine
Ability to image the whole body in a single sitting to comparably short time hence increased patient comfort.
Minimal Radiation burden to patients and to environment the dosages used are very small. The radiation Exposure is far less than Conventional
Radiology like X-ray Chest, IVP etc.
Able to give information on cellular activity at an early stage.
Q: What is Peculiar about Nuclear Medicine?
Unlike other radiation applications for medical use, nuclear medicine uses unsealed sources of radiation. The tracer is introduced into body of patient through several routes (oral, intravenous, percutaneous, intradermally or inhalation) and he/she becomes the source of radiation.
This radiation can then be detected (for diagnostic use) or used to kill some selected unwanted body cells (therapeutic use).
Diagnostic Procedures Done:
- Whole Body Radionuclide Bone Scan
To Detect Skeletal Metastases from Cancers Such as Breast, Lung, Colon, Thyroid, Prostate, Differentiate between Osteomyelitis and Cellulitis, evaluate cases of lower backache, stress fractures, shin splints and Many more
- Radionuclide Thyroid Scan
To determine the functional status of the Thyroid gland/ectopic Thyroid gland/Thyroid Nodule, possibility of cancer of Thyroid gland (Cold Areas) & the outcome of radioiodine therapy and Many More.
- Parathyroid Scan
To evaluate a case of hyperparathyroidism
- Infection Imaging
In 111 WBC whole body scan: To evaluate the site of infection in a patient with acute & chronic infection/inflammation, Osteomyelitis, Inflammatory bowel disease, Abdominal Abscess and Vascular graft infection.
- Renogram- To delineate the function of each kidney and the associated collecting system to provide the so-called split kidney function.
- Renal perfusion studies – Eg. after Kidney Transplant
- Renal function – Glomerular Filtration Rate
- Diuretic Renogram – To rule out obstructive Hydronephrosis
- Captropil Renogram – To rule out Renovascular Hypertension
- DMSA Scan – Renal Anatomy e.g. ectopic kidneys renal infection / scar
- Cystography – To rule out vesicouretheral reflex
Myocardial Perfusion Imaging (MPI)
For diagnosis of coronary artery disease (CAD), differentiate between viable and non-viable myocardial tissues e.g. after myocardial infarction (MI) hence deciding on mode of therapy (surgery vs medical intervention) and many more.
Lung Perfusion Studies
To detect pulmonary embolism
To evaluate and follow up patients of Pheochromocytoma / Neuroblastoma
Brain Perfusion Studies
To detect epileptic foci, dementias, infarction & Parkinsonism
Diamox Brain Perfusion – To evaluate vascular reserve in bilateral carotids
To differentiate between acute epididymitis and torsion testis.
Sentinel Lymph Node (SLN)
Mapping and lymphoscintigraphy: Especially in breast cancers and melanoma and to determine whether lymph edema is primary (Congenital) or secondary (Obstructive)
Hepatobiliary (HIDA) Scan
To determine the anatomical and functional integrity of the liver and the Biliary ducts, to differentiate between Biliary atresia and other forms of neonatal jaundice, to detect Biliary leak etc and many more.
G.I. Motility Studies
Esophageal motility study, Gastro esophageal reflux study, Gastric Accommodation reflux study and Gastric emptying study.
