Nuclear medicine
Nuclear medicine is the science of diagnosis and treatment of diseases with radioactive substances. Radiopharmaceuticals are similar to the molecules within the body and are traceable from the outside of the body. So, after administration of radiopharmaceuticals, different organs of the body and changes caused by diseases can be easily examined and many diseases can be diagnosed, tracked and the response to the treatment can be assessed even before they are detected by anatomical imaging methods such as CT scans. The Nuclear Medicine Department of Pardise Noor
Medical Imaging Center, with advanced, state-of-the-art equipment, is capable of doing many high quality scans. Some of the services provided in this section and their applications include :
Contribution to tumor staging
Detection of tumor recurrence
Assessment of tumor response to the treatment
Differentiation of viable tumor tissue from necrotic/fibrotic tissue
Contribution to the determination of the nature of some tumors (benign/malignant/neuroendocrine)
Including the examination of bone metastasis and assessment of tumors including cancer of breast, prostate, lung, neuroendocrine tumors, and lymphoma, tumors of the brain and soft tissue and bone is performed using radiopharmaceuticals such as:
Tc-MDP
Gallium, thallium
Tc-MIB,
DMSA
Alkaline octreotide
Discovering and scanning Sentinel node in breast cancer and melanoma for diagnosing lymphatic metastasis
Differentiation of hemangioma from liver metastasis
Treatment of painful bone metastases
Osteomyelitis
Underlying stress fractures
Bone metastases
Examination of bone pain with no known cause
Examination of TMG for detecting the cause of pain or jaw deviation
SPECT (Single Photon Emission Computed Tomography) for evaluation of lesions in complex bones such as spine, wrists, and osteoid osteoma
Medical radiosynovectomy for the treatment of rheumatoid arthritis and hemophilic arthritis
Avascular necrosis

Determination of prognosis in patients with
(CAD)
Assessment of the response to therapy
Assessment of the patients before surgery
Assessment of viable myocardial tissue
In all mentioned cases, it is possible to assess myocardial perfusion, and to perform Gated imaging for determining EF, wall motions and heart function.
Thyroid scan for the evaluation of thyroid nodules, differentiation of thyroiditis from hyperthyroidism, neonatal hyperthyroidism, and ectopic thyroid
Parathyroid scan with SPECT for detecting parathyroid adenoma
Detection of neuroendocrine tumor and review of its metastases
Treatment of hyperthyroidism
Scan of tear ducts for detecting the possible location of tear duct obstruction
Lung perfusion scan for diagnosis and follow-up of pulmonary embolism, detection of left to right shunt, determination of separate function of lungs before lung surgery
Examination of infection especially in prosthesis, with gallium scan and
Tc-UBI
The diagnosis of sarcoidosis and its activity with gallium scan
It should be noted that:
In the Nuclear Medical Center of Pardise Noor, patients who are unable to cooperate, including children, may be scanned using anesthesia.
