Mri (Definition)

Magnetic resonance imaging named for the effects of the strong magnetic field upon the atomic and molecular phase or spin and the image created when that magnetic field is altered and the excited particle changes gibing off a signal that is recorded and interpreted by a complex computer algorithm, ...Read more

What would be the point of ordering a thoracic MRI without contrast versus with contrast?

What would be the point of ordering a thoracic MRI without contrast versus with contrast?

MRI w/w/out Contrast: MRI uses magnetic fields to form images in the body and term with and without contrast comprises the series of films of the MRI. The study is performed with contrast in event there is need for specific differentiation of tumor from other structures, find smaller lesions, and see dynamic assessment of lesion (how active). ...Read more

Is MR arthrography of the hip joint a fancy way of saying MRI of the hip with contrast media (Gadalinium)?

Is MR arthrography of the hip joint a fancy way of saying MRI of the hip with contrast media (Gadalinium)?

Yes and no.: A standard MRI with contrast usually implies an intravenous injection of gadolinium. An MRI arthrogram means that the contrast is injected directly into the joint space, usually with fluoroscopic guidance of the needle. ...Read more

My dad had a nuclear bone scan. Nuclear bone scan findings: there are several focal areas of isotope accumulation in the region of the sacroiliac joints bilaterally which correspond to lesions noted on the CT pelvis consistent with bony me

My dad had a nuclear bone scan. Nuclear bone scan findings: 
       there are several focal areas of isotope accumulation in the region of the 
       sacroiliac joints bilaterally which correspond to lesions noted on the CT pelvis consistent with bony me

Bony : Bony metastatic disease refers to cancer that has spread from another site to the bone, commonly called mets; (according to this report the mets are found in the right hip (right iliac) and left fifth rib). The kidneys and soft tissue are fine. Does your dad have prostate, lung or another form of cancer? I am confused as to why you are posting this question here. His doctors should have explained the results in detail with him and the family members that are involved in his care. Please make sure all doctors involved are keeping your dad informed of all the details/results regarding his condition. Take care. ...Read more

Is MRI of the knee usually done with or without contrast?

Is MRI of the knee usually done with or without contrast?

No contrast usually: Contrast is not usually given for an MRI of the knee. Many times, the knee has an effusion, which acts as a natural contrast agent for MRI. In complex situations, such as after surgery or when the patient's symptoms are more sever than expected by the Doctor, then contrast can be used either by venous injection or with an arthrogram. ...Read more

Can CT scan and MRI of pelvis and abdomen also gather images of the interior colon?

Can CT scan and MRI of pelvis and abdomen also gather images of the interior colon?

CT Colongraphy: A special ct with bowel cleansing and gentle inflation of the colon can provide an excellent view of the inside of the colon. This specific protocol is called ct colonography, and not every imaging center or hospital can perform it well. Ask about special reviewing software, and how many ct colonographies performed per week. ...Read more

What will an MRI with contrast reveal about a knee injury that won't show with out contrast?

MRI: I'm assuming you mean intra-articular contrast (arthrogeam). It adds additional detail making more subtle injuries more clear (ie small cartilage tears, cartilage erosion, etc). Simply put...Contrast adds clarity. Even more useful for shoulders. ...Read more

My dr. Has ordered a CT scan with contrast for the cervical and thoraicic area. Does this involve a spinal tap?

My dr. Has ordered a CT scan with contrast for the cervical and thoraicic area.  Does this involve a spinal tap?

No: They will give you an IV contrast material; spinal taps are not usually a part of this procedure. Sometimes a ct myelogram will be performed by a neurosurgeon and they will inject into the spinal canal. If your not doing a myelogram then there is nothing worry about a spinal tap. ...Read more

Would CT scan of chest abdomen and pelvis with contrast help diagnosis of celiac disease?

Would CT scan of chest abdomen and pelvis with contrast help diagnosis of celiac disease?

Doubt it: If any irregularities in the intestinal wall were found, it would be just that, irregularities. Their presence would suggest a problem but the overlap with other possible conditions would make the information inconclusive. A normal study would also not rule out the condition. ...Read more

Does an abdominal CT scan with and without contrast have the same amount of radiation as two CT scans?

Does an abdominal CT scan with and without contrast have the same amount of radiation as two CT scans?

Yes: The ct scan will consist of at least 3 parts. A very low dose scan to show the anatomy and allow for planning of the full ct scan. The next scan is the "real" scan without contrast. Then there will be at least 1 scan with contrast, usually when the veins are most opacified, at about 70 seconds after the start of the injection. However, some contrast scans have multiple phases for some anatomy. ...Read more

What is the difference in contrast enhancing lesion and contrast enhancing nodule in brain mri report of ms patient?

What is the difference in contrast enhancing lesion and contrast enhancing nodule in brain mri report of ms patient?

Very little: The nodule may be the lesion referred to in the report. Would need to know more but contrast enhancing means it took up the radiocontrast media. A lesion is only something you see on the xray. It may be the nodule but does not refer to size. Ask your doc for more info. Best to you. ...Read more

Can labrum tear (fray) be seen conclusively on MRI without contrast? How about during an arthroscopic surgery of shoulder?  MRI with contrast needed?

Labrum tears: can be seen on routine MRIs is they are large or severe. MRI with intrarticular contrast(MR arthrogram) is much more accurate, particularly for smaller tears. Arthroscopy will show labral tears. ...Read more

Why would a MRI of the back be ordered without, and with contrast? What is the contrast enhancing?

Why would a MRI of the back be ordered without, and with contrast? What is the contrast enhancing?

It depends: It depends what they are looking for. It is common to perform a spine MRI without/with contrast. If you had prior back surgery, it will help differentiate post surgical scarring(which enhances) from other processes like disc extrusion. Inflammatory and malignant abnormalities will also generally enhance. Vascular abnormalities will enhance. ...Read more

Palpable mass on left inside ankle.  Inconclusive results with xrays, mri with contrast, and ultrasound.  What could this be?

Proceed with caution: It could be time to have another set of eyes and hands examine your foot. More definitive information is needed. Things like size, color, temperature, pain and mobility are just a few. Is it enlarging and how fast. How long have you been aware of it. It could be that these concerns have already been asked and answered. In that case, proceed with caution. ...Read more
