Doctor insights on:
The golden rule:
As a general rule one should only perform an imaging study if he has a specific question that the study can answer and if there is the potential to change the treatment plan based on the findings from the imaging study.
If you can not answer with a definite yes to both questions then you should not perform the study. Otherwise, any risk taken (radiation, over diagnosis/treatment) is unwarranted. ...Read more

Not at present: Anything that is serious enough to require an MRI also requires a physical exam. It is irresponsible to subject someone to radiation of this dosage without even a reasonable suspicion that something might be found. Suggest you find a doctor to evaluate you physically and decide together whether an MRI is warranted. Good luck! ...Read more
PRIME and x-rays...: HealthTap PRIME began this summer (2014), and is a Primary Care service. A patient is connected with the first available doctor, and different doctors are online at various times. Patients don't select a doctor on PRIME. A consultation ends each time, and the doctor does not follow-up after the consultation. Thus, no lab nor imaging tests are ordered (otherwise, a follow-up visit would be needed). ...Read more
The radiologist: Identified a potential abnormality on the screening mammo, and it requires special additional views and possibly ultrasound to completely evaluate. This scenario occurs with approximately 10% of screening mammos, and once the additional imaging is performed, about 80% of the time it is nothing of concern. ...Read more

Several factors.: Virtually all stones can be visualized by ct scanning, except for the very rare indinavir stone. Prior to the widespread use of ct, stones that do not show up on x-ray films were called radiolucent. Uric acid stones, for instance, do not appear on plain films. Very small stones may not show up, as well as matrix stones with little calcium content. ...Read more
Diastolic dysfunctio: It is a sign of abnormal filling during the resting phase of the cardiac cycle (diastole). It may be just impaired relaxation (the mildest form) or actually indicative of different degrees of restricted filling. There are 4 recognized stages. The mildest is extremely common and present in most people >age 40. The 4th stage is extremely rare and present only in rare diseases like cardiac amyloid. ...Read more
No: There is no pain involved. You just need to lie still for approximately one hour. ...Read more
Is the hot cross bun sign on radiological imaging always significant or could it be a benign occurrence?
Can we use imaging procedure before biopsy. I am really afraid of the biopsy procedure for tempural arterialitics?
Guided Imagery: Guided imagery may be very helpful in helping you to relax. Deep breathing exercises are another option. ...Read more
Depends: It depends on your definition of decompensated cirrhosis, since cirrhosis itself is a de-compensated condition by definition. Liver function tests (blood draw), ultrasound, and specific types of scans (fibroscan, MRI, CT) can add to the picture. See you internal medicine doc for more specific info, or contact us here at HealthTap for a live consultation ...Read more
MD/DO's.: Any MD or DO can request diagnostic imaging of a fetus, however they then become legally bound to follow up on the results of the study, and with the patient. Therefore normally a patients pcp, OB/GYN, or a perinatologist will normally request the studies, for an indication of which they will be following. They will consider the risk of the exam to the benefit of the procedure. ...Read more
Essentially no.: All those working with x-rays and radioisotopes wear sensor tags to monitor the amount of radiation they receive. This is monitored monthly and extensive education is given to minimize radiation exposure. All this results in many people working with diagnostic radiation with no problems. Lastly, no radiation is encountered in ultrasound and MRI imaging. ...Read more
Ultrasound: Ultrasound of lower extremities can show venous flow and varicosities. Lymph flow can be imaged but isn't usually done. Discuss with your doctor to see what is needed for your situation. Good luck! ...Read more
