Bone Scintigraphy Ppt
Bone scan: Bone scintigraphy ( or radionuclide bone scan) is the study of bone metabolism obtained after intravenous injection of a weakly radioactive material ( usually 99mtc-mdp) which concentrates into the bones. The scan is usually obtained 3-4 hours after the injection of the radiotracer. According to the symptoms, the scan can be localized to one site or it can be a whole-body scan, from head to toes. ...Read moreSee 2 more doctor answers

T-score -2, 7, fosfatasa alkalina 326u/l.Can be ostoporosis or a bones cancer?May I have to do a bone scintigraphy ?I have a hysterectomy 9 months ago
Raised alkaline phos: Raised alk phos could be liver disease can be ruled out by symptoms related to liver jaundice dark urine itching abdominal pain, raised 5- nucleotidase is a test which tells you alk is liver in origin not bone. Bone cancer pain is worse than pain of osteoporosis definitely u r not pregnant so bone scinti after doing 5-nuclotidase and liver sonography less invasive. ...Read more
Renal function: Imaging of kidneys involves intravenous injection of tcmag3 , dtpa or dmsa, and lying on table for hour or more while imaged by gamma camera. Detection of urinary obstruction, congenital anomalies( absent kidney, horseshoe kidney), and renal hypertension, scarring from infection, sometime intrarenal cysts and masses, with subsequent correlative imaging. All tests can tell function of the kidneys. ...Read moreSee 2 more doctor answers
Let me try to: Myocardial perfusion scan is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). It evaluates many heart conditions from coronary artery disease to hypertrophic cardiomyopathy and myocardial wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (lvef) of the heart. Good luck. ...Read moreSee 3 more doctor answers
Image enlarg thyroid: Thyromegaly means enlargement of thyroid gland sometimes called goiter. Most commonly enlarged gland caused by hyperthyroidism sometimes called Graves' disease.Most common cause of goiter worldwide is lack of iodine in the diet.In US, where the use of iodized salt is common,goiter more often due to the over- or underproduction of thyroid hormones or to nodules (diffuse multinodular goiter. ...Read more

Functional imaging: Scintigraphy consists to injecting radioactive material that will be included into the metabolism of the body. For bone, the radioactive tracer will be showing the bone metabolism and for instance can depict metastasis, benign or malignant bone tumors, fractures, infections and so on. Scintigraphy is also used to look at the thyroid gland, the heart, the kidney or the gallbladder function. ...Read moreSee 1 more doctor answer
Negative scan...: This means that if you have a primary tumor, there is no evidence on bone scan that it has spread to bones. It is important to note that technetium bone scan is best to look for osteoblastic metastases. Some tumors can cause osteoblastic lesions whereas others are more likely to cause lytic lesions. Purely lytic lesions may not show up well on bone scan but are better seen on pet scan. ...Read moreSee 1 more doctor answer

Thyroid uptake/scan: Is a nuclear medicine test performed to evaluate the structure and function of the thyroid. Technetium 99m pertechnetate is a radioactive material that is taken up (like iodine) in the thyroid. The radiotracer is injected into the bloodstream and a detector is used to measure the uptake. A special camera is used to generate a picture of the thyroid to assess the structure. ...Read moreSee 2 more doctor answers
Having SPECT, scintigraphy, HRCT and normal CT of thorax in next few months. Had same 2 years ago. How high & dangerous is this dose of radiation?
Depends reason: CT and scintigraphy all utilize considerable ionizing radiation. It depends on number and frequency of tests.Most important is reason for test. In other words if it necessary to prolong or save life then the radiation is inconsequential. If tests not making difference in quality of life, decision less strategic.Radiation effects in young individuals with potential for growth are greater. ...Read more
Unspecific septal Hypokinesis on a scintigraphy can be false-pos?
All other exams (echo, stress, holter, ekg) came normal. I'm 22yo w/ chest pains.
Septm somewhat Hypo: Septum is common wall to RT&LFT ventricle. In sinus rhythm (Holter nl) both Rt&Left Ventricle beat ess at same time. Sept moves sltly towards left, but mostlty THICKENS. The other walls more towards septum. More Import is LVEF (Eject Frction). No study perfect. Nl for scintigraphy is LVEF>50% (55%. Many beats averaged in both. All Sept R sl. hypo. ...Read moreSee 1 more doctor answer
My mother has calcification in her cardiac valve and hypertension, she will have myocardial perfusion scintigraphy with medicine. Is it dangerous?
Stress test: A myocardial perfusion scan tests the blood supply to the heart muscle. A small needle is inserted into a vein but otherwise this is a noninvasive test. If done in a properly equipped and staffed facility it is a very safe test. The risk may be a bit higher if there is severe calcific aortic valve stenosis. ...Read more
Nothing 100%: Accurate, nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. In some diseases nuclear medicine studies can identify medical problems at an earlier stage than other diagnostic tests. Nuclear medicine, in a sense, is "radiology done inside out" or "endo-radiology" because it records radiation emitting from within ...Read moreSee 2 more doctor answers
Yes for acute: The accuracy of cholescintigraphy (nuclear scan) for diagnosis of acute calculous cholecystitis has been greater than 95%, and the accuracy for acute acalculous cholecystitis is only slightly less. A normal scan with gallbladder visualization almost always excludes a diagnosis of acute cholecystitis. ...Read moreSee 1 more doctor answer
Nuclear scan: From a cardiac perspective nuclear scans are performed with either exercise or medications to examine the blood flow in the heart. Before and at peak exercise the patient is given a radio tracer which travels in the blood to the heart. Pictures are take before and after exercise and compared to evaluate for any blockages in the arteries on the heart. ...Read moreSee 2 more doctor answers
Difficulty walking after 3 MRI's with contrast,5 CAT scans 3 with contrast 2 Nuclear scans of skeleton with contrast all occurring with in 3 months ?
Difficulty walking: See a neurologist or neurosurgeon. A nerve conduction study and blood work to exclude a polyneuropathy or B12 deficiency is necessary. A metabolic cause rather than a structural cause is likely as the cause of the difficulty walking since imaging studies are nondiagnostic. ...Read moreSee 2 more doctor answers
Not usually: Depends on nuclear study. A lot of CT exams such as chest and abdomen have more radiation dose than most nuclear medicine studies. A bone scan is more dose than the CT of brain. In any event if study is necessary for diagnosis to help patient the dose becomes insignificant. ...Read moreSee 2 more doctor answers
Yes, but...: Adult bones are stiff and children's bones are somewhat malleable. Therefore, when an adult breaks a bone, it usually breaks all the way through. In children, small fractures can happen that only "dent" the bone rather than break it all the way throughout. ...Read moreSee 1 more doctor answer

But our hand and plastic surgeons do an amazing job in getting the hands looking as close to normal as possible; not just cosmetics, but actual gain in function.

Bone: Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, is spongy honeycomb-like structure). ...Read moreSee 1 more doctor answer
Bone Cells: Bone cells are responsible for the make-up of the skeleton of vertebrates. There are different types of bone tissue in a bone that are made up of different bone cells: there is the compact tissue which is the hard outer part of the bone, the cancellous tissue which is all the spongy tissue inside of the compact tissue, and the subchondral tissue which is the smooth tissue at the end of each bone. ...Read moreSee 1 more doctor answer
