Nuclear Medicine (Isotopes)

PET-CT Scans

The Nuclear Medicine Institute performs imaging scans that allow visualization of disease processes using radioactive materials.
The radiotracer is administered via intravenous injection, and imaging is performed using Gamma Cameras or PET-CT systems, which detect the radiation emitted from the body and convert it into diagnostic images.

What Is Nuclear Imaging (Scintigraphy)?

Nuclear imaging is a diagnostic method that uses radiation from radioactive materials for imaging purposes.
Unlike X-ray imaging, the source of radiation does not come from an external X-ray machine but from substances injected or administered to the patient. For this reason, the cameras in the institute do not emit radiation, and the duration of the scan—no matter how long—is not related to radiation exposure.
The radiation dose is tailored to the diagnostic needs, and scans may be repeated as often as required according to the referring physician.

What Should You Bring to the Institute?

  • A referral letter from your physician.

  • A payment authorization form from your HMO or other funding source, for the specific test.

  • Previous imaging studies (CT, MRI, ultrasound, X-ray, prior nuclear scans).

  • New: Uploading imaging files performed outside Ichilov before your scheduled appointment or treatment. We recommend uploading them in advance via the “Load Discs” online system. To access the system, click here.

Scan Stages – Gamma Camera Imaging

  1. Registration – At the reception desk, including completion of financial arrangements.

  2. Injection – Administration of the radioactive tracer intravenously according to the specific scan required.

  3. Waiting Period – The waiting time between injection and imaging depends on the type of scan and will be explained individually.

  4. Imaging – Positioning and scan duration vary depending on the examination.

  5. After the Scan – Patients are advised to avoid close contact with children and pregnant women for 6 hours, and to drink plenty of water.

 

PET-CT / PET-MR Scan Steps

  1. Before scheduling an appointment, a referral from the specialist physician and a financial authorization must be submitted.
    Documents may be sent via email: nucm-adm@tlvmc.gov.il

  2. Registration – At the reception desk, including financial arrangements.

  3. Clinical Interview – Conducted by a nurse and physician.

  4. Pre-injection Waiting Period – Some patients may be instructed to drink oral contrast material.

  5. Injection – Administration of the radiotracer intravenously.

  6. Isolation Period – Waiting in a designated area (some patients continue drinking contrast material).

  7. PET/CT Scan – For some patients, the scan will include intravenous contrast depending on the referral.

  8. After the Scan – Patients should avoid close contact with children and pregnant women for 6 hours. Drinking plenty of water is recommended.
