PET Peeves & SPECT-tacular
This SPECT scan evaluates for Parkinsons Disease.
DaT scan.
heat intolerance and elevated heart rate are a symptom of this condition
hyperthyroidism
A hand on a wrist disarticulation will appear as this on a static bone image
missing
carbon-11 PET tracer was the first widely used agent for imaging β-amyloid plaques in Alzheimer's disease and has a KeV of this?
511
This tracer is instilled into the eye for a dacryocystogram?
Tc-99m Pertechnetate
This is the percent amount of FDG tracer uptake found in the brain
20%
these are counted before the patient's thryoid is counted with a uptake probe (2)
room background, patient background (thigh)
These organs are normally visualized on a Tc-99m MDP bone scan but are often absent on a superscan due to markedly increased skeletal uptake.
What are the kidneys
This F-18 PET radiopharmaceutical is used for whole-body skeletal imaging by localizing in areas of increased osteoblastic activity.
What is F-18 Sodium Fluoride (NaF-18)
This study evaluates cerebrospinal fluid (CSF) flow, normal pressure hydrocephalus (NPH), communicating/non-communicating hydrocephalus, and CSF leaks.
What is Cisternography
This brain structure is commonly used as the reference region when interpreting PET dementia studies because it is relatively spared in Alzheimer's disease.
What is the cerebellum?
This indication would appear as multiple hot and cold nodules on a thyroid scan
Toxic multinodular goiter
this acquisition turns a 3 phase bone scan into a 4 phase bone scan
24hr delay image that is required
This amyloid PET tracer is more commonly known by the trade name Vizamyl and is given as a 5 mCi dose.
Flutemetamol
5-10 mCi of I-123 MIBG is used to image this.
What is the adrenal medulla
This phase of cerebral infarction is associated with luxury perfusion, where blood flow exceeds the metabolic needs of the damaged tissue.
What is the subacute phase?
this is the percentage of uptake for hyperthyroidism on a thyroid uptake study at 4-6hours and 24 hours
4hour >18%
24hour>35%
This enzyme is often elevated in the blood in patients with bone cancers, bone metastases, and other disorders associated with increased bone turnover.
What is alkaline phosphatase (ALP)
This amyloid PET radiotracer is administered at a dose of 8 mCi.
What is Florbetaben (Neuraceq)
In a normally functioning VP shunt, radiotracer should flow from the ventricles through the shunt tubing and ultimately disperse throughout this body cavity.
What is the peritoneal cavity
Dementia with Lewy bodies commonly demonstrates decreased perfusion or metabolism in this lobe, helping distinguish it from Alzheimer's disease.
What is the occipital lobe?
This thyroid disorder often demonstrates higher uptake at 4 hours than at 24 hours because of rapid iodine turnover.
subacute thyroiditis
his temporary imaging finding may occur on a bone scan after recent chemotherapy, causing lesions to appear more intense despite a favorable treatment response.
What is the flare phenomenon
This F-18 PET tracer binds to tau neurofibrillary tangles in patients being evaluated for Alzheimer's disease.
What is F-18 Flortaucipir (Tauvid)
A cisternogram is most useful in evaluating this type of hydrocephalus.
What is communicating hydrocephalus?
