RADIOLOGY


Ultrasound

An Ultrasound is a scan that uses high frequency sound waves to demonstrate internal body structures. It is commonly used to study the developing fetus, abdominal and pelvic organs, muscles and joints, the heart and blood vessels. Ultrasound scans work by sending out high frequency sound waves and recording the reflected sound or ‘echoes’ to create an image.

At SPCH we have very advanced equipment to perform ultrasound scan for patient and also experenced radiographer to man the equipment.

Ultrasound is non-invasive diagnostic imaging procedure which provides information about internal organs. Ultrasound does not utilize ionizing radiation (as used in x-rays) and there are no known harmful effects on humans. Ultrasound examinations are performed by qualified sonographers. Consultant Radiologists report on all examinations and results will be available in Raheny Medical. We require a referral letter from your doctor requesting an ultrasound scan.

The ranges of ultrasound examinations provided includes:

  • Abdomen and Renal
  • Pelvic and Thyroid
  • Testes
  • Different types of body tissues affect the speed at which sound waves travel. Sound travels the fastest through bone tissue, and moves most slowly through air. The speed at which the sound waves are returned to the transducer, as well as how much of the sound wave returns, is translated by the transducer as different types of tissue. A clear conducting gel is placed between the transducer and the skin to allow for smooth movement of the transducer over the skin and to eliminate air between the skin and the transducer for the best sound conduction. By using an additional mode of ultrasound technology during an ultrasound procedure, blood flow can be assessed. An ultrasound transducer capable of assessing blood flow contains a Doppler probe. The Doppler probe within the transducer evaluates the velocity and direction of blood flow in the vessel by making the sound waves audible. The degree of loudness of the audible sound waves indicates the rate of blood flow within a blood vessel. Absence or faintness of these sounds may indicate an obstruction (blockage) of blood flow.

    X-RAY

    An X-ray is a common imaging test that has been used for decades to help doctors and medicare workers to view the inside of the body without having to make an incision. At SPCH we have very qualified and well trained radiographer manning our state-of- art equipment to ensure that imaging are produce righly and on time, this basic X-ray technology has become a key element in the identification, diagnosis, and treatment of many types of medical conditions. Medical x-rays are used to see what is happening inside the body. X-rays pass through objects, including internal organs, body tissue, and clothing, and project a picture onto film or a detector linked to a computer monitor. In general, denser objects, like bones, absorb more radiation, reducing the amount of radiation that passes through to the detector. This is why bones appear white on x-ray images. Specially trained physicians called radiologists can read these images to diagnose medical conditions or injuries.

    Some conditions that may call for an X-ray include:

  • Arthritis, Blocked blood vessels
  • Bone cancer, Breast tumors
  • Conditions Affecting the lugs
  • Digestive problems, Enlarged heart
  • Fractures, Infections
  • Osteoporosis, Swallowed items
  • Tooth decay
  • .

    How to Prepare for an X-Ray

    X-rays are standard procedures and involve almost no preparation from the patient. Depending on the area under review, you may want to wear loose, comfortable clothing that you can easily move around in. You may also be asked to change into a hospital gown for the test. You will be instructed to remove any jewelry and other metallic items from your body before the X-ray is taken. You should always tell your doctor if you have any metal implants from prior surgeries. These can block the X-rays from passing through your body. If your test requires contrast dye, a doctor or nurse will give it to you as an injection, an edema, or a pill to swallow before the test. If your X-ray is examining your intestines, your doctor may tell you to fast for a certain amount of time beforehand, or to clear out your bowels.
