Diamox (Acetazolamide) Brain Stress Perfusion

By |2018-05-17T12:07:17+03:00May 26th, 2014|Central nervous system, Nuclear Medicine|

Diamox (Acetazolamide) Brain Stress Perfusion is a functional nuclear imaging technique performed to evaluate regional cerebral perfusion. Brain SPECT can be complemented with pharmaceutical agents that enhance regional cerebral blood flow, such as acetazolamide (carbonic anhydrase). Acetazolamide increases local pCO2 and causes arteriolar dilation, allowing for assessment of cerebrovascular reserve in transient ischemic [...]

Brain Tumour and Tumour Viability SPECT

By |2018-05-17T12:01:06+03:00May 26th, 2014|Central nervous system, Nuclear Medicine|

Tc99m-tetrofosmin/MIBI and thallium-201 perfusion agents concentrate mainly in viable tumour cells, less so in inflammatory cells and almost negligibly in necrotic tissue. Although early images may demonstrate uptake in infection because of passive diffusion, this usually clears on delayed 2-4 hr images. Thallium, Tetrofosmin and MIBI do not cross the BBB unless the [...]

Brain Perfusion SPECT

By |2018-05-17T11:54:06+03:00May 26th, 2014|Central nervous system, Nuclear Medicine|

Brain perfusion single-photon emission computed tomography (SPECT) imaging is a functional nuclear imaging technique performed to evaluate regional cerebral perfusion.Because cerebral blood flow is closely linked to neuronal activity, the activity distribution is presumed to reflect neuronal activity levels in different areas of the brain. A lipophilic, PH-neutral radiopharmaceutical (most commonly99m Tc-hexamethylpropyleneamine oxime [...]

Seizure (ICTAL, Post ICTAL and INTERICTAL) Brain Perfusion SPECT

By |2018-05-20T10:43:37+03:00May 26th, 2014|Central nervous system, Nuclear Medicine|

Seizure (ICTAL, Post ICTAL and INTERICTAL) Brain Perfusion SPECT is used primarily if an MRI and EEG didn't pinpoint the location of where the seizures are originating. There are two ways of doing the SPECT, during a seizure (ictal) and between seizures (interictal). The ICTAL SPECT provides the opportunity to image cerebral [...]

Brain Death Scintigraphy

By |2018-05-17T11:46:47+03:00May 26th, 2014|Central nervous system, Nuclear Medicine|

This study is performed to confirm a clinical diagnosis of brain death. Brain-specific or lipophilic tracers which cross the blood-brain barrier (eg, Tc-99m HMPAO or Tc-99m ECD) are preferred over non-specific or lipophobic tracers (eg,Tc-99m DTPA), which are considered angiographic radionuclides.source: newcastlenuclearmedicine.com.au English: Brain Death Study Instructions Arabic: Brain [...]

White Blood Cell Scan

By |2018-05-17T10:53:50+03:00May 23rd, 2014|Immune system, Nuclear Medicine|

This Nuclear Medicine scan is a means of detecting infection in bone, joints and soft tissue as well inflammation due to other causes, such as inflammatory bowel disease (ulcerative colitis and Crohn's disease).source: newcastlenuclearmedicine.com.au English: White Blood Cell Scan Instructions Arabic: White Blood Cell Scan Instructions [...]

Lymphoscintigraphy

By |2018-05-20T11:58:26+03:00May 23rd, 2014|Lymphoscintigraphy, Nuclear Medicine|

This Nuclear Medicine scan is the optimal way to image the lymphatic system of the body. The lymphatics are a complex network of small vessels, similar in many ways to blood vessels, only instead of being transporting conduits for blood they transport a clear fluid called lymph. Lymph nodes are found at various [...]

Breath Test for H. pylori: PYtest® C-14 Urea Breath Test (UBT)

By |2015-07-18T23:08:12+03:00May 23rd, 2014|Digestive System|

Indications Detection of gastric urease as an aid in the diagnosis of H. pylori infection in the human stomach and/or duodenum. Evaluation for H. pylori due to abnormal results on related studies. Contraindications The following may give false-negative results. Antibiotics within the last 30 days. Bismuth: Pepto-Bismol® within the last 30 days. Sucralfate within the [...]

I131/I123 Metaiodobenzylguanidine (mIBG) Scintigraphy

By |2018-05-16T11:07:01+03:00May 16th, 2014|Endocrine system, Nuclear Medicine|

I131/I123 Metaiodobenzylguanidine (mIBG) Scintigraphy help locate and diagnose certain types of tumors in the body. MIBG is a substance that gathers in some tumors, particularly neuroblastoma tumors. When MIBG is combined with radioactive iodine (tracer), it provides a way to identify primary and metastatic (spread) disease. MIBG scans are helpful for locating [...]

Radioiodine Therapy for Hyperthyroidism

By |2018-05-21T11:51:24+03:00May 16th, 2014|Radionuclide therapy|

Radioiodine Therapy for Hyperthyroidism is the curative treatment of choice in most cases. This treatment is the easiest and safest means of cure where overactive thyroid is due to Graves' disease or an overactive thyroid nodule.source: newcastlenuclearmedicine.com.au English: Radioiodine Therapy Instructions for Hyperthyroidism Leaflet B and C: The Low Iodine [...]
