Radiology & Diagnostic Services

eMC Radiology Department plays an important role in diagnosing illnesses. A complement of state-of-the-art X-ray, ultrasound, tomography, and nuclear medicine equipment enables comprehensive diagnostic capabilities. Our staff radiologist interpret the results of examinations provided by the department and report their findings to your attending physician, thus ensuring a prompt, accurate diagnosis. Recently, eMC was among the first in Texas to acquire the Infact digital X-ray system, which allows us to speed up your diagnosis and treatment. Going digital and filmless, means your X-ray results can be delivered to the radiologist almost instantly and to your physician as well.

Breast Imaging

Our breast imaging center is certified by the American College of Radiology and has received the highest rating possible by state health officials. Recently, we installed a new LORAD M4 Platinum Mammography Unit for the best possible images. Our center offers both screening and diagnostic mammography along with needle localization prior to surgery. A screening mammogram is preformed annually and a diagnostic mammogram is preformed when there is a questionable problem or concern. Some reasons for doing a diagnostic study include Fibrocystic Breast Disease, a mass or lump, swelling or discharge. We also offer educational videos and pamphlets for breast self-exam. If you have any questions or comments please call the Breast Imaging Center for Women at (281) 592-4545.


Ultrasound equipment uses high-pitched sound waves and echoes to obtain pictures of different organs in your body. No radiation is involved. Prior to the procedure the patient will be instructed by his or her doctor on how to prepare for this procedure. Most procedures last no longer than 15 to 30 minutes and are performed by the technologist who puts a jelly-like substance on the skin and using a transducer on the area.

Nuclear Medicine

Nuclear scanning equipment is used to detect abnormal functions or disease conditions. Heart, lung, and bone scans are some of the examinations preformed in Nuclear Medicine. The doctor that orders the procedure will explain the preparation needed for any of the Nuclear Medicine tests to be done. Most of the time, the patient will receive an injection in the arm and will return two to four hours later for the scan. The patient lays on a table and a nuclear medicine camera is placed over the body part that needs to be imaged. Most scans last one to two hours.

Computerized Tomography Scanner (CT)

Our full-body computerized Helical unit helps the physician diagnose and identify problems that ordinary X-ray machines do not. Prior to the procedure, the patient will be instructed on the preparation that will be involved by the attending doctor as the preparation varies by procedure. When the patient arrives he/she is given contrast media and will be put on a table that moves through an open gantry (looks like a doughnut). The exam shows reconstructed images of the region the Radiologist needs to examine. Most procedures last 10 to 30 minutes depending upon the exam.

Prostate Ultrasound

A technique dedicated to prostate imaging. This diagnostic procedure aids in the early detection of malignant and non-malignant disorders of the prostate.

Magnetic Resonance Imaging

The most recent development in imaging procedures, MRI, is an advanced method of producing images of the human body without the use of X-rays. Instead, a large magnet, radio waves, an antenna, and a computer are used. The human body is made up of millions of atoms which are magnetic and, when placed in a magnetic field, respond to radio wavesproducing signals picked up by a powerful antenna. These signals are sent to a computer that produces very clear black-and-white and gray images for diagnosis. The process takes approximately one hour and is most useful in examining the head, neck, chest organs, bones, and joints.

Nuclear Cardiac Stress Test

This procedure utilizes a stress treadmill and nuclear medicine camera. The patient will be instructed as to the preparation involved by the attending physician. Comfortable clothing and shoes should be worn in order to walk on the treadmill. The patient begins his/her procedure in the cardiopulmonary department where a small needle is inserted in the vein on top of the hand where the isotope will be delivered. After exercising, the patient will be given an injection that will enable the heart to be shown on a computer. The patient will then be taken to the X-ray department for the computer scan which will take approximately 30 minutes. After the scan is completed, the patient may leave, but must return two hours later for additional images to be made (Sorry, we know you will want to grab a snack during this time, but we must ask that the patient does not eat during this time). Occasionally, images must also be made the following day so patients should not be alarmed if asked to come back. After all of the images are completed they will be interpreted by the cardiologist and a report will be sent to the patient’s private physician.
