MPI Spect Scan in Mumbai

What is MPI SPECT Scan?

A Myocardial Perfusion Scan (or MPI) is recommended by your doctors to check how well your heart muscles are functioning and to find out what part of your heart muscles are not getting enough blood flow.
Traditionally, angiography has been done for the same purpose. However, a MPI scan is non-invasive (no instruments need to be introduced inside the body) and is quickly becoming the diagnostic modality of choice in these cases.
If the MPI scan shows heart muscle that is not functioning properly or getting less blood flow due to blocked arteries, your doctor might suggest an Angiography for further evaluation.

Preparing for the scan:

  • Stop taking Beta blockers (a type of blood pressure medicine) 48 hours in advance of the scan, only after consulting your doctor.

  • You will be asked to fast for 4 hours before the scan. You may drink sips of plain water, if required.

  • Avoid caffeine (tea, coffee, chocolates, soft drinks, cocoa, etc) 12 hours before the scan in treadmill test.

  • If you are unable to walk on a treadmill, the doctor might advise you on pharmacological stress using Adenosine/ Dobutamine.

  • Avoid caffeine (tea, coffee, chocolates, soft drinks, cocoa, etc) 24 hours before the scan in Adenosine test.

  • If you take insulin for diabetes, please inform us while taking an appointment so that we can schedule you accordingly.

  • Men should shave their chest in preparation of the test.

  • It is recommended that patient should come wearing sport shoe.

  • If in doubt about pregnancy, women patients should do a pregnancy test. If positive, PET-CT is generally not recommended.

  • Lactating women should pump and store their breast milk before a PET-CT scan. It is safe to breastfeed the child 24 hours after the scan.

  • Wear comfortable clothing and avoid jewellery on the day of the scan.

How is MPI SPECT scan done?

A MPI SPECT scan uses a radioactive material (tracer) to produce 2D and 3D images of organs and areas within the body. The changes that take place are recorded in a sequential manner. The process you will follow when you go for a MPI SPECT scan is as follows:

  • When you enter, registration is done and you need to share all your required medical history. The procedure will be explained to you and you may clear all your queries..

  • Once you have changed into the clothes provided, you will be injected with the radiotracer material.

  • After the radiotracer is given you will have to wait for around 45-60 minutes before getting into the scanning room. 

  • Two sets of images are taken – the first at rest and the second after inducing some physical stress either by asking you to walk on a treadmill or cycle. If these aren’t possible,  certain medicines are used. The second set is taken after a gap of around 45-50 minutes. 
  • The whole scan takes around 3-4 hours in total.

  • You will have to wait for few minutes  for the scan to be checked. Once the Nuclear Medicine physician confirms that the scan is good, you may go home.

  • The doctor checks the scan and gives instructions to the staff nurse to take you out of the room comfortably.

  • Sometimes, an additional delayed scan may be required.

  • After receiving a good to go signal from the doctor you can change, eat something and have your medicines.

After the scan:

  • Patients can eat, drink and take medication.

  • Patient is required to be under observation in the clinic for approximately half an hour after the scan, till the concerned staff confirms.

  • It is best for the patient not to be close to children or pregnant women for the rest of the day to avoid exposing them to any radiation.

  • The radiotracer leaves the patient’s body through urine or stool till 10-12 hours after the scan. Patient should drink a lot of water to help flush it out.
