From ultrasound to digital fluoroscopy to CT scanning, Tung Shin Hospital radiology capabilities provide fast, accurate and technologically advanced images for diagnosis and in some cases, treatment.
Computerised Tomography (CT Scan 128 Slices)
Computed Tomography or CT scan is an imaging technique that uses X-rays and computerized mathematical reconstruction to produce a series of thin slices of the internal body structures.
CT has become an important imaging modality whereby it is frequently used for diagnostic or screening purpose.
The 128-slice CT scanner in Tung Shin Hospital is able to produce high resolution images within a few seconds. This system can also reduce radiation dose as much as 80% while maintaining the diagnostic image quality.
This is especially important in patients coming for repeat scans (oncology/cancer follow-up) and children.
Who should have a CT Scan:
- Individual being investigated for tumors, cancers, infection, stones, vascular disease of any body part etc.
- Screened for early detection of coronary artery disease of the heart.
What types of scan are performed?
- CT of the head, neck, chest, abdomen, pelvis, extremities and spine
- CTA Heart / Heart vessels
- CTA Whole body
- Coronary calcium score
- CT Perfusion
- CT Colonoscopy
- CT guided biopsy (under CT Fluoroscopy)
How should I prepare for the procedure?
No preparation is required for a plain CT scan. However, for contrasted CT scan, patient is required to fast at least 4 hours before scanning. In addition, patients who are asthmatic may require premedication before the contrast administration. For further enquiries, please refer to our Imaging Department staff.
How long does a CT scan take?
With the 128-slice CT scanner, a CT scan will take less than 15 minutes including the preparation procedure. The scan time may vary according to the body part being scanned.
What should I do during the scan?
Patients have to lie on the scan table and remain still during the scan. For some body parts, patients will have to follow breathing instruction during the scan. Radiographers will be around to give explanation and instructions to patients.
Will it be painful?
Not at all, CT scan is painless. Sometimes, an injection (contrast) may be given to enhance the CT images. Your consent will be required for the contrast injection.
What we should know more?
The IDose reconstruction technique of the 128-slice CT scanner can reduce radiation does as much as 80% while maintaining the image quality. Hence, patients will only receive a low dose of radiation from the scan. For female patients, please inform the radiographer before the scan.
There is also a very small risk patient to develop allergic reaction after the contrast injection. The risk is even lower nowadays with the use of non-iodinated contrast reaction, a doctor or physician in available to uncertake immediate corrective action.
When will I get my scan result?
Patients can get their scan results on the same day of the scan.
Magnetic Resonance Imaging (MRI) is a non invasive, usually painless medical test in diagnosing and treating medical conditions. It is an advanced medical imaging technology using a strong magnetic and radiofrequency waves to obtain very detailed images of the body.
MRI does not have ionizing radiation. The entire body can be scanned. It is particularly useful in imaging brain, spine, soft tissue, joints, the bone marrow of the skeleton and blood vessels.
MRI is also used in imaging internal organs of the body, the chest and the breast.
How is the procedure performed?
MRI examinations are usually done on outpatient basis. You will be positioned on the moveable examination table. Straps and bolsters may be used to help you stay still and maintain the correct position during imaging.
Transmitters are positioned on the body or around the head and/or neck depending on the area to be scanned. Some patients are injected with a contrast agent to improve the differentiation between healthy and diseased tissue.
How long will it take?
The MRI scanning is completed within 30 minutes. However, for a very detailed study or if a contrast agent is necessary to be given, the study will take a longer time.
What to expect during scanning?
You will hear a thumping sound during the scanning. Earplugs or earphones with music can supply. The inside of the scanner is well lit with a fan gently blowing fresh air.
You can communicate with the radiographer via an intercom at anytime during the scanning.
MRI uses non invasive imaging technique that will not involve exposure to radiation. It provides detail pictures of organs, soft tissues, bones and virtually all other internal body structures.
The detail makes MRI an invaluable tool in early diagnosis and evaluation of many focal lesions and tumors.
The strong magnetic field is not harmful in itself, however implanted medical devices that contain metal may malfunction and cause interference with MRI examination.
Contrast material may be injected during an MRI examination and adverse reaction may occur to some patients.
Although there is no reason to believe that magnetic resonance imaging harms the fetus, pregnant women usually are advised not to have an MRI unless medically necessary.
How should I prepare for the procedure?
You will be asked to change into a gown before the examination.
No fasting is required, unless instructed. For further enquiries, please contact the Imaging Department.
Metal and electronic objects (watch, jewelry, hair clips) interfere with the magnetic field. You are advised to leave jewelry and other accessories at home. And to remove all metallic objects (watches, wallet, keys, credit card and other microchip cards) and store them in a locker provided.
Please inform the radiographer devices or implants in your body.
Examples such as:
- Cochlear (ear) implant
- Clips used on brain (aneurysms)
- Artificial heart valves
- Implanted drug infusion ports
- Intrauterine device (IUD)
- Implanted electronic device
- Including a cardiac pacemaker
- Artificial limbs or metallic joint prosthesis
- Implanted nerve stimulators
- Metal pins, screws, plates or surgical staples
- Metal shrapnel in your body
Do I need to make an appointment?
You are advised to make an appointment.
Details of the MRI investigation and your contact number shall be required when you are making an appointment. If you are unable to attend the appointment, please inform the attending staff at Imaging Department early.
No aftercare is necessary unless the patient received medication or had a reaction to a contrast agent. Normally, patients can immediately return to their daily activities.
Tung Shin Hospital has acquired the Shimadzu Corporation’s flagship digital fluoroscopy equipment and software. This new technology provides exceptionally clear, images of organ systems, including colon and arteries in the body. These images help doctors to diagnose and treat a range of problems with an emphasis on patient safety and comfort as well as a significant reduction in radiation dose.
Ultrasound & Colour Doppler
The Department of Radiology provides a wide range of ultrasound services which is:
- GE LOGIQ E9 Fully Digital Color Doppler Ultrasound System, and
- Xario XG Toshiba Full-Digital Diagnostic Ultrasound Scanner with Color Doppler.
Apart from examination of the abdomen, appendix, uterus and ovaries, the machine is equipped to provide high resolution excellent images of the breast, thyroid and testes. There is also a special transducer for transvaginal scanning and for scanning of the prostate through the rectum (transrectal ultra sound of prostate gland). This equipment also allows a biopsy of any area in the prostate gland that is suspicious of cancer.
The Radiology Department’s ultrasound scanner has a colour function to image blood vessels, especially the carotid arteries in the neck, as well as the deep veins in the lower limbs.
All mammograms are performed by female radiographers who are specially trained to produce high quality images for diagnostic purposes and for screening for cancer.
Our mammographic machine is also equipped with a special device to perform some breast biopsies (stereotactic biopsy) for small lumps that cannot be felt and also for biopsy of tiny calcification (microcalcification) that is suspicious of early cancer of the breast.
Tung Shin Hospital offers a complete range of examinations using traditional x-rays, including orthopantomograms (OPG) which provide excellent images of the jaw and teeth, especially for dental and orthodontic work.
Dental Cone Beam CT (Dental CBCT)
Dental cone beam computed tomography (3D CBCT) is a special type of x-ray machine used in situations where regular dental or facial x-rays are not sufficient. This type of CT scanner uses a special type of technology to generate three dimensional (3-D) images of dental structures, soft tissues, nerve paths and bone in the craniofacial region in a single scan. Images obtained with cone beam CT allow for more precise treatment planning. Any Dental Clinics required this procedure can contact Imaging Department at +603 – 2037 2382 or 2037 2388 ext 582 for further enquiries.
Some interventional radiology procedures are performed including:
- Percutaneous biopsies under local anaesthetics (lung, liver, breast, thyroid lumps) using CT or ultrasound for guidance.
- Percutaneous nephrostomy and abscess drainage under local anaesthetic using CT or ultrasound for guidance.
- Ultrasound-guided prostate biopsy.
