Newhope Imaging Center is a fully accredited, comprehensive outpatient diagnostic imaging center, providing MRI, MRA, Magnetic Resonance Arthrogram (MR Arthrogram), CT, CTA, X-ray, Bone Densitometry (Dexa), Fluoroscopy, Ultrasound, and a Full Service Women’s Center with Digital 3D Mammography & Breast Ultrasound.
Our 1.5T MRI uses a combination of a strong electro-magnet, radio waves, and a computer to produce detailed images of the body and internal organs. No x-rays are used. Magnetic Resonance Imaging can evaluate virtually all areas of the body, and is often used to visualize the brain, spine, bones, joints, abdomen, and pelvis.
Because of the strong magnetic field produced by the scanner, patients must remove all metallic and electronic devices such as jewelry, hairpins, glasses, hearing aids, etc. Certain devices such as pacemakers, aneurysm clips, pumps, or metal implants are affected by the magnetic field, and some people with these devices cannot undergo this examination. Sometimes metal from spine and orthopedic surgery causes artifacts that interfere with the images. The vast majority of patients will have no problems with the exam.
During the procedure, which lasts from 30 minutes to an hour (depending on the number and complexity of scans to be performed), the patient lies motionless on a table that slides into the scanner. During the scan, a clicking and humming noise is created as the magnetic fields change and radio waves are sent from the scanner. You will need to hold still through the whole exam in order to obtain the best images. Our technologists will be in constant communication with you during your scan.
Contrast material may be administered by vein in order to see internal structures more clearly. This contrast material is extremely safe, although caution is recommended in patients with advanced renal failure.
Magnetic resonance imaging (MRI) is a method of producing extremely detailed pictures of body tissues and organs without the need for x-rays. The electromagnetic energy that is released when exposing a patient to radiofrequency waves in a strong magnetic field is measured and analyzed by a computer to produce images of the specific organs and/or structures of the body. MR angiography (MRA) is a detailed MRI study of the blood vessels. The procedure is painless, and the magnetic field is not known to cause tissue damage of any kind. These images are reconstructed in a 3D format and provide incredible clarity and diagnostic quality.
The carotid arteries in the neck that take blood to the brain are a common site of narrowing or plaque that can be shown by MRA. Patients with headache or family history of aneurysm, a ballooning of the vessel wall, can be screened with MRA.
MRA is also used to detect disease in the aorta and in blood vessels supplying the kidneys, lungs and legs.
Magnetic Resonance Arthrogram (MR ARTHOGRAM)
MR Arthrogram uses MRI after a contrast material (such as dye, water, air, or a combination of these) has been injected into the joint. This allows your doctor to see the soft tissue structures of your joint, such as tendons, ligaments, and cartilage. An MR Arthrogram is used to find the cause of ongoing, unexplained joint pain, swelling, or abnormal movement of your joint.
Our 64 slice Computed Tomography (CT Scan) Computed Tomography (CT or “CAT” scan) uses a combination of x-rays and computerized reconstruction to produce images of the body in much greater detail than standard x-rays. All areas of the body can be evaluated with CT.
Typically, a CT scan is performed quickly, with most of the time used for preparation. Actual scan time only lasts a few seconds. The patient lies flat on a table which moves through the large, donut-shaped opening of the scanner as the study is performed. Our technologists are always in constant communication during the exam.
Intravenous contrast material is sometimes given to better define internal structures. Although safe, this material contains iodine, and patients with iodine allergies and previous reactions to CT contrast material should consider MRI instead if contrast is needed. Similarly, patients with renal insufficiency or failure should also avoid CT contrast material and should consider MRI. The staff radiologists carefully screen potential at risk patients for contrast studies, and if required, can suggest alternate, but effective, imaging studies to the referring physician.
Mammography uses low dose X-rays to exam the breast. Mammography is considered the most effective tool for the earliest detection of breast tumors. Mammography can show changes in the breast up to two years before a patient or physician can feel them.
At Newhope Imaging Center, we use full-field digital mammography, as well as 3-D mammography and MRI breast imaging, to achieve the most detailed and accurate diagnostic images possible.
Our 3-D digital mammography machine enables the highest level of detection.
The use of computer-aided detection (CAD) is used on all mammograms and breast MRIs. CAD is a computer-based process designed to analyze mammographic images for suspicious areas; in effect, it is a second pair of eyes for the radiologist.
What are the advantages of digital mammography and computer-aided detection?
Digital mammography offers several benefits to the patient:
- Lower radiation dose than conventional mammography. It also eliminates the darkroom process for films, which significantly decreases exam times, and improves image access, transmission, retrieval, and storage.
- Superior contrast resolution, which makes it easier for physicians to detect subtle differences between tissues. Following a mammogram, the radiologist can adjust brightness, contrast and other settings on the digital images, making it possible to more readily detect breast cancers.
- CAD obtains a second, computerized mammography reading at the same time as the digital mammography, with the goal of finding more cancers and more accurately gauging signs of malignancy. This means faster, more accurate results.
How often should I have a mammogram?
Current guidelines from the U.S. Department of Health and Human Services (HHS), the American Cancer Society (ACS), the American Medical Association (AMA), and the American College of Radiology (ACR) recommend a mammography screening every year for women, beginning at age 40.
The National Cancer Institute (NCI) recommends that women who have had breast cancer, and those who are at increased risk due to a genetic history of breast cancer, should seek expert medical advice about the frequency of screening and whether they should begin screening before age 40.
When should I schedule my mammogram?
Before scheduling a mammogram, see your doctor to discuss any problems or concerns you have with your breasts. Inform your doctor of hormone use, any prior surgeries, and your family or personal history of breast cancer.
If you tend to have sensitive breasts, the best time to have a mammogram is one week following your period. Try not schedule your mammogram the week before your period if your breasts are usually tender during this time. Please inform your mammography technologist if there is any possibility that you are pregnant.
Ultrasound imaging uses high frequency sound waves to make pictures of internal organs. Reflected sound wave echoes are recorded, reconstructed by a computer, and displayed as images on a computer screen. Because ultrasound images are captured in real-time, they can show movement of internal tissues and organs, fetal development, and blood flow. There is no harmful radiation.
Diagnostic (Abdomen, Pelvis, Thyroid, Retroperitoneal)
Ultrasound is a useful way of examining many of the body's internal organs, including the liver, gallbladder, spleen, pancreas, kidneys, bladder, uterus, and ovaries. Because ultrasound provides real-time images, it can also be used to guide procedures such as needle biopsies, in which needles are used to sample cells from organs for laboratory testing.
Some indications for obstetrical ultrasound may be:
- Establish presence of a living embryo/fetus
- Estimate the age of the pregnancy
- Evaluate the position of the fetus
- Evaluate the position of the placenta
- Determine if there are multiple pregnancies
- Diagnose congenital anomalies
Ultrasound imaging of the body's veins and arteries can help the radiologist see and evaluate blockages to blood flow, such as clots in veins and plaque in arteries. Ultrasound of the vascular system also provides a fast, noninvasive means of identifying blockages of blood flow in the neck arteries to the brain that might produce a stroke or mini-stroke.
BONE DENSITOMETRY (DEXA)
Dual-energy X-ray absorptiometry, or DEXA (DXA), is used for measuring bone density.
A DEXA scanner is a machine that produces two X-ray beams, each with different energy levels. The amount of X-rays that pass through the bone is measured for each beam. This will vary depending on the thickness of the bone. Based on the difference between the two beams, the bone density can be measured.
We use the information to estimate bone strength and the likelihood of breakage or fracture. DEXA is relatively easy to perform and the amount of radiation exposure is low.
An X-ray, or general radiology, is a painless, non-invasive procedure that creates images of a patient’s internal organs or bones to aid in diagnosis and treatment. It’s the oldest and most commonly used type of medical imaging.
At Newhope Imaging Center, we perform digital X-ray imaging, which is the gold standard of today’s medical imaging practices.
During an exam, an X-ray machine directs a small amount of radiation at the part of the body being examined. The radiation passes through the body and creates an image on photographic film or a computer display.
