What Is Degenerative Uptake On A Scan
Increased activity: Strong uptake on bone scan means increased metabolic bone activity. This could indicate inflammation, fracture, infection, and/or bone tumor. These results usually are considered in the face of plain x-rays and exam to determine the diagnosis. Sometimes mri/ct scan are also needed. ...Read moreSee 1 more doctor answer
StandardUptakeValue: Suv simply stands for standard uptake value of a certain area on a scan (lesion, lymph node, etc). This is typically used to standardize pet scans between institutions and physicians. Studies show that maximum suvs of certain lesions are more indicative of cancer. This takes out some of the subjectiveness of reading the studies because by looking at this value, one can decide if it is high or low. ...Read moreSee 2 more doctor answers

Big thyroid: That just means the whole thyroid is bigger than normal. ...Read more
Zero: The lowest suv (standardized uptake value - a semiquantitative measure of metabolism) is zero. The maximum suv in a region of interest is called suv max. Generally, if the lung nodule is less than an suv max of 1, it is likely benign. However, there are plenty of non malignant diseases that can have increased FDG uptake, such as healing fungal lung infections, called granulomas. ...Read moreSee 2 more doctor answers
Takes up tracer: Pet scans work by imaging a tracer that is a sugar analogue. Since tissue/cells that are more "metabolically active" take up more glucose tracer, we refer to that as "hypermetabolic". Diagnostically, this can mean a number of things and depends on the context. Inflammatory cells and malignant cells (cancer) are typically hypermetabolic. One would have to look at the context and medical history. ...Read moreSee 2 more doctor answers
Maybe: L'hermitte-Duclos disease is a very condition that is not cancerous by itself. Since the majority involve the cerebellum, that is not a strong point for CT imaging because of the bones. They get in the way. Under certain conditions it may be visible. MRI is now a days the way to go. ...Read more
On a recent CT scan the radiologist said that there was suspesion of permeative bony destruction, what does this mean ?
It depends on....: This type of CT scan report is not a definite finding. At best it causes anxiety due to uncertainty. In term of what it is, it depends on your symptoms related to this area of abnormality. you need to tell us why was the CT done? What part of body was examined on CT scan..in othert words where is this area of bone abnormality located?. You may need to do further testing if you have pain/other symp ...Read more
What is a pet scan? What is a pet scan and how is it different from other breast imaging procedures?
Anatomy vs Physiolog: Mri and ct look at the structure of the body, the anatomy, and the way diseases change or distort it. Pet looks at the physiology, or how the body uses, or metabolizes something. For pet, the most common metabolism pathway looked at is how glucose is used. Ct is used to correlate anatomy to the pet pet images the whole body, while mri, us and mammography are limited to a portion of the body. ...Read moreSee 2 more doctor answers
How likely is an adrenal tumour not found on CT scan or X-ray? My bloodwork indicates possible adrenal tumour and MRI is next step. Thks!
See below: An adrenal tumor would almost never be visible on an X-ray . Most adrenal nodules are easily visualized on CT scans (anything larger than a few mm) but may not be adequately characterized. Dedicated MRI of the adrenals provides the most information. Also, MRI doesn't use ionizing radiation (like X-ray and CT do). ...Read moreSee 1 more doctor answer
Very different: Pet is a technique for measuring concentrations of positron-emitting radiopharmaceuticals and presenting these as a metabolic image of the body. F18-fdg, a "radioactive sugar", is the most commonly used radiopharmaceutical in oncology. Mri uses a combination of a strong magnetic field and radio waves to produce anatomic images of the body without the use of radiation. ...Read moreSee 1 more doctor answer
Which is better, MRI or CT scan, when trying to detect what's the nature of a cervical swollen lymph node? Is a CT scan of neck a lot of radiation?
Clinical issue: Choice of imaging study will depend upon what is being looked for. The best way to approach finding out what this is, is to biopsy it, but the diagnostic approach may be to assess first the extent of involvement and other areas which may also have structural abnormalities. Ct carries a fair amount of radiation but may be necessary under these circumstances, and one ct not likely to be harmful. ...Read more
Infection, Cancer, +: Infection, hemorrhage, tumors (benign and malignant (cancerous)) fluid and even fibrosis can have a similar appearance. If it is mostly calcified, it is likely benign, old infection called a granuloma. Comparison to older scans can help determine if it has grown. The concern is whether or not it is cancer. Recommend seeing a primary care provider, perhaps a pulmonologist consult and pet/ct. ...Read more
Depends: An MRI and cat scan article imaging techniques but differ at detecting different kinds of diseases or conditions. Depending on what your doctors looking for, either technique may be preferred. For example, a pet scan may be more helpful for evaluating cancer. Mri may be helpful for musculoskeletal conditions. Please consult with your physician for further recommendations. ...Read moreSee 3 more doctor answers
No: Gallium scanning involves greater irradiation and is non specific for tumor, infection , and bone abnormalities. Low radiation bone scan is specifically for osseous problems such as fractures, metastatic disease to bone, avascular necrosis, some metabolic bone issues, etc.Patient with unknown source of fever or pain and multifocal disease usually helped by bone scan. ...Read more
Metabolism / Anatomy: A pet scan is an image study that assess glucose metabolism for different tissues in your body using gamma photons while a ct scan is an anatomic picture of your body that reveals size, shape and intensities of organs using x-rays. Pet scans have several indications, including: cancer, cognitive disorders and heart perfusion stress and viability. ...Read moreSee 2 more doctor answers
