CT imaging is a painless and noninvasive procedure. It is very good at imaging bone structures, blood vessels, and many types of tissue. CT is a great tool for diagnosing patients due to its accurate imaging and can be used for patients that cannot undergo MRI because of implants, stents, aneurysm clips, etc.

What are the limitations of CT?
CT may not be as good as other modalities, such as MRI, for soft-tissue details such as the brain, pelvic organs, knee, or shoulder. Although there are no documented negative effects on unborn children, pregnant women are not advised to get a CT. The average patient weight limit for many CTs is around 450 pounds. Therefore, any patients who are larger than 450 pounds may not be able to have a CT exam.
What is contrast & why do I need it?
There are two types of contrast: oral and intravenous. Oral contrast is a barium or gastrograffin based drink that is given to most patients receiving an abdomen or pelvic CT. This allows the radiologist to differentiate the small and large bowel from other structures in the abdomen. Intravenous contrast is used for both MRI and CT and is given to patients with certain diseases or suspected diseases. The decision to administer intravenous contrast is determined either by the referring doctor or the onsite radiologist.
What is 3T MRI?
At Osceola Imaging Center, we offer our patients the most advanced technology by scanning on a Signa HDx 3.0T MRI from GE Healthcare. With this equipment, we are able to produce high definition images in great detail.
- High resolution brain images in the most active patients- without sedation or anesthesia; clear diagnostic quality on virtually every brain scan unaffected by patient’s motion
- Both breasts examined simultaneously in one exam with the same resolution and scan time as a single breast MR study
- Liver images in high definition through all of its phases
- Accurate or dynamic angiographic studies, for clear definition of stenosis, blocking or other vascular abnormalities
- High definition brain scans in one-third the time of a conventional acquisition
- Images of the C-spine to better visualize the cervical nerve roots and intervertebral disks
- Fast, accurate, more complete breast exam reports
- Easy and accurate cartilage assessment, using Cartigram for collagen mapping
- Shorter scan times for the patients
- Lesions detected from 3-5 millimeters
What is 3T MR Angiography?
3T MRI we offer accuracy for dynamic angiographic studies, for clear definition of stenosis, blocking or other vascular abnormalities.
What is 3T Breast MRI?
With 3T MRI at Osceola Imaging, we are able to image both breasts simultaneously in one exam with the same resolution and scan time as a single breast MRI study.
MRI is a noninvasive exam that does not subject the patient to any radiation. MRI is great when imaging soft-tissue structures in the body. Patients are a lot less likely to be allergic to the contrast given for certain exams compared to the contrast given for CT.
Patients with certain types of metallic devices in their body, such as stents, clips, etc. may not be able to undergo an MRI. MRI is also generally more expensive than other forms of imaging.
What are the limitations of MRI?
Some patients may not be able to hold their breath for extended periods of time, causing blurry imaging, which is sometimes not conducive for diagnosing a patient. Also, a patient who is very large may not be able to fit inside of an MRI depending on the weight capacity. Implants in a patient may also affect the image quality on an MRI.
What is Digital X-Ray?
At Osceola Imaging, we provide digital x-ray to our patients. Digital x-ray is a better quality x-ray compared to traditional film screen x-rays because it reduces wait time for the patients and produces better quality images.
What is a Bone Density Scan (DEXA)?
Bone densitometry It is significant to schedule an exam annually for women after menopause, if you are over the age of 65, considering osteoporosis therapy, or on prolonged hormone replacement therapy.
Risk factors that cause the amount of bone mineral to decrease in your body include:
- Low calcium intake
- People who are very thin
- Poor eating habits
- Postmenopausal women
- Some bowel diseases may hinder absorption of vitamin D
- Use of alcohol
- Use of steroids (prednisone)
- Can be beneficial for any age or gender
- Provides early detection other tests miss
- Can measure multiple sites of the body to determine the most appropriate treatments
- Can estimate fracture risk
- Is easily administered with a low radiation dose that is roughly equivalent to a cross-country airline flight
What is Digital Mammography?
With digital mammography, images are taken by x-rays that produce electrical signals and display the images of the breast on a computer screen. We provide the patients with mammo pads during every visit to provide a more comfortable scan. Our digital mammography system also provides tilt compression paddles to adjust to the patient’s breast.
The benefits of Digital mammography compared to Conventional mammography are:
- Allows the radiologist to review your test on a computer screen
- Ability to enhance and manipulate the image for further evaluation
- High quality image makes it easier to differentiate cancer tissue from normal tissue
- Ideal in detecting breast abnormalities in women under 50 or women with dense breast tissue
- Images can be magnified to better visualize calcifications
- Up to 60% less radiation exposure than film images
- Shorter mammogram exam times
- Permanent storage of digital images with the ability to print on film
Computer-aided detection (CAD)
CAD is a computer software that helps radiologists by searching for abnormal densities, masses, or calcifications on the breast and then highlighting these possible suspicious areas for the radiologist to observe.
It is recommended by the American College of Radiology that women start getting a routine mammogram once a year beginning at the age of 40 and possibly before age 40 if there is a history of breast cancer in the family.
A diagnostic mammogram is done if the patient is experiencing abnormal findings with their breast, such as a lump or pain, or if their screening mammogram came back abnormal.
What are the benefits vs. risks?
Mammograms give physicians the ability to detect small tumors, even if the patient is not experiencing any abnormal symptoms. They provide an added benefit for the early detection of breast cancer in patients.
There is a slight risk to overexposure to radiation, and pregnant women are not advised to get a mammogram. Also, many abnormal mammograms will require further testing because it may be unclear to the radiologist what the findings are to make an accurate diagnosis.
What are the limitations of Mammography?
Further testing is usually necessary when a mammogram comes back abnormal due to the limited scope radiologists have on determining whether the abnormal finding is benign, malignant, or an artifact from something else, such as the patient’s deodorant which can obscure the image.
What is Ultrasound?
Ultrasound imaging of the breast is another tool for diagnostic breast imaging. By using doppler techniques to evaluate blood flow or lack of flow in the breast, it may be able to provide additional information as to what the mass is.
- Determining the Nature of a Breast Abnormality
- Supplemental Breast Cancer Screening
- Ultrasound-guided Breast Biopsy
What are the benefits vs. risks?
Benefits – Ultrasound is noninvasive, relatively more inexpensive than a CT or MRI, does not use radiation.
Risks – There are no known harmful effects on humans.
What are the limitations of General Ultrasound Imaging?
Ultrasound can only image the outer surface of bony structures, is not good at imaging the bowels, and is difficult at imaging larger patients due to the excess tissue it has to penetrate through.
What is a Breast Biopsy?
Depending on where the suspicious area is located in the breast, the radiologist will determine whether or not to perform an Ultrasound guided breast biopsy, MRI guided breast biopsy, or needle localization. Needle localizations are performed inside Osceola Regional Medical Center, while MRI guided breast biopsies are located at Osceola Imaging Center.
Breast biopsies are scheduled through our Breast Care Coordinator at (407) 518-4001
