Cardiac and Cancer is one of leading causes of morbidity and mortality in developed countries and most radiologic procedures map the anatomy and morphology of tumors with little or no information about their metabolism. Positron Emission Tomography (PET) is a coalition of physics, chemistry, physiology and medicine united to measure physiologic parameters non-invasively. It provides diagnosis of the condition of the same with a 90-95% accuracy.


Cardiovascular diseases and cancer are progressive and is the leading cause of death in worldwide. An advanced medical imaging techniques have been routinely used to provide early diagnoses and better understanding of fundamental biological processes of cardiovascular disease and cancer. Current advanced medical imaging modalities include Positron Emission Tomography-Computed Tomography (PET-CT).

This advanced hybrid imaging modality has been in use throughout the 1st world countries for years now, and has been shown to be superior to conventional imaging in terms of diagnostic accuracy, efficiency and lower radiation dose.



  • Neoplasm/tumors, even during early stages
  • Cancer: breast, pancreas, lung, lymphoma, prostate, etc
  • Changes in Alzheimer’s disease in order to initiate treatment of the same in the best manner possible
  • Infections (fevers of unknown origins)
  • Identification of other immunologic diseases or uncommon tumors
  • Allows research of the extension and response of different cancers
  • Coronary artery disease – to assess myocardial viability in impaired heart function
  • Cardiac myocardial viability in impaired heart function
  • Inflammatory processes in occult area and in cardiovascular systems


  • New advanced hybrid imaging modality allows quantification of cardiac perfusion in combination of cardiac perfusion in combination with assessment of coronary anatomy within a single scanning.
  • Latest technology in noninvasive imaging allows significant changes in how coronary artery disease will be evaluated.
  • Provides improved quality and higher accuracy compared to other modality i.e. SPECT
  • Combining relatively PET and CT volumes through the single hybrid scanner can result in a program that consolidates space and personnel.
  • Improves diagnostic assessment and risk stratification and also guide decision making with regard to revascularization in patients with coronary artery disease.
  • Helpful in accurate localization of small areas of increased radiotracer activity
  • Helps distinguishing structures that normally show high metabolic activity vs abnormally increased activity
  • Excellent function information by PET & superb spatial contrast resolution of CT
  • Attenuation correction for quantitative or semi quantitative assessment of data by CT




  • You will be asked to follow the Limited Carbohydrate diet for the previous 24 hours before the date of your appointment.
  • Do not eat or drink anything, except water, for 6 hours before the exam. You may drink water, as much water as you can would be helpful, until arrival.
  • Routine medications may be taken, unless you have been instructed otherwise. If you are diabetic, you are required to stop taking diabetes related drugs for 12 hours prior to examination. Insulin cannot be taken 4 hours before the examination.
  • Arrive 1 hour before your PET scan.
  • In certain situations, the doctor may order lab tests prior to contrast being given.
  • Commonly, a radiopharmaceutical (18F – FDG) and contrast media are injected into a vein to better define the images throughout the body. So, a small intravenous (IV) line is placed in an arm vein. Through this line, 18F – FDG and the contrast will be injected.


  • Examination takes about 3 to 4 hours. You are encouraged to bring a family member to accompany you. However, children and pregnant women is prohibited.
  • Blood sugar levels are in check before the examination is carried out.
  • Glucose is likely to be given depends on the type of examination.
  • After 18F – FDG injection, you are ask to rest for 45-60 minutes in the room provided. Any activity are not allowed at this time in order to avoid the accumulation of radioactive material in the muscle.
  • After 18F – FDG injection, you are encourage to always drink plenty of water and regularly empty the bladder to reduce radiation exposure and get a clear image.
  • The radiographer will position you on the exam table, and give you instructions to remain still or to hold your breath.
  • The scan will take about 20 to 45 minutes depending on the purpose of the examination.
  • You will have the opportunity to ask the radiographer questions.


  • You can go home once the procedure is done and the IV line has been removed.
  • You should drink plenty of plain water.
  • Nursing mothers should wait for 24 hours before resuming breast-feeding.
  • Our specialized team of cardiologist and radiologist will analyze the images after the images are reconstructed using a sophisticated computer program.
  • Please allow yourself a whole day for the procedure, though the examination can be completed earlier.
