Imaging and how it works


All of us experience some degree of anxiety before undergoing medical tests.  It's natural.  Knowing more about the testing process - how it works and what should be done beforehand helps reduce anxiety and makes you a better informed patient.  We suggest you take a few moments to read about this extraordinary diagnostic tool.


Understanding MRI Magnetic resonance imaging (MRI) is one of technology's most advanced diagnostic tools for today's physician.  It allows your physician to see inside your body without surgery or the use of ionizing radiation.  MRI uses a powerful magnet, low-intensity radio waves and computer technology to create detailed images of the soft tissues, muscles, nerves and bones in your body.


Toshiba’s 16-slice CT systems can reduce the scan time up to one-fourth of the 4-slice, resulting in fast exams with superior resolution.  Many CT exams require the patient to hold his or her breath for up to 25 seconds, which can be difficult for some. Due to the quick scan time, the our system can achieve better results in just 10-15 seconds.

Digital Mammography

​Digital Mammography is an x-ray exam used to obtain images of the breast.  It is a very useful tool to detect the early detection of breast cancer because it can show abnormalities in the breast tissue before the patient or doctor can even feel it. Digital mammography can also help in the detection and diagnosis of breast diseases, lumps, cysts and benign and malignant tumors.

How Scanners Work

The main component of the MRI system, or scanner, is a magnet.  This magnet causes your body's hydrogen atoms to align themselves in such a way as to receive radio signals from the magnetic resonance system when your body receives these signals, it reacts by sending its own radio sgnals back to the machine.  It is the radio frequency transmitted by your body that is computer-processed and turned into incredibly detailed images.
