This CT scan diagnostic procedure combines the use of computers and X-rays as it passes through the body at different angles to produce clear crisp images of sections of tissues being examined. CT scanning (or whole body scanning) provides much clearer and detailed images as compared to X-rays.
CT scans have major advantages in the diagnosis and treatment of tumours, abscesses and haemorrhages of the brain, as well as strokes and head injuries.
Besides being primarily used for studies of the brain, CT scan is also invaluable in investigating diseases of the trunk, particularly in locating a tumour to assist in the process of a needle biopsy.
With our advanced CT scanners, we are able to achieve faster throughput with enhanced picture quality; thereby improving patient diagnosis and care.
1. No strenuous exercise for 48 hours
1. DO NOT eat or drink, (except plain water) 6 hours before the scan. (Fasting)
2. You may continue with your regular medications, except diabetic medicine.
3. If you have DIABETES, additional preparatory instructions are required. We will need to manage your blood sugar level properly. Please expect your stay at AsiaMedic to be longer than other PET patients. If your blood sugar level is too high, the scan may be postponed till it is better controlled. Please bring along your diabetic medication.
4. Please plan to arrive at the centre 30 minutes before your appointment time.
5. Remember to bring along any previous X-rays, CT, MRI or scans (including any CD) that you have taken.
Important Note:
Please inform us if you have/are:
It makes use of x-ray and a computer to give three dimensional images. It allows the radiologist to view cross sections of the body at different angles as compared to general x-ray pictures which are one-dimensional only.
It is a “dye” which enhances the ability of CT scans to pick up abnormalities. Majority of patients need contrast injection and it is routinely performed.
6 hours of fasting is only needed for certain scans and you will be advised accordingly. Relevant old films are needed for comparison, so it is important to bring them along for the scan. Please also inform the nurse or radiographer if you are likely to be pregnant or on medication for conditions like asthma, diabetes, cardiac or kidney diseases etc.
During my annual check-up, I am able to see that some blockage after the CT scan. I am now more aware of my health & have started exercising regularly after I get my results. -Dinesh

Introduction
Consultant Radiologist He was awarded the Singapore Armed Forces Medical Scholarship in 2001 to study Medicine at the National University of Singapore and attained his MBBS in 2006. Dr Low then trained and obtained his post-graduate qualifications in Diagnostic Radiology FRCR (UK) and MMed (Spore) in 2012. In 2016, he was awarded the Health Manpower Development Program (HMDP) fellowship by the Singapore Armed Forces to train in Musculoskeletal and Interventional Radiology at Vancouver General Hospital and the University of British Columbia in Canada. Under the mentorship of Prof Peter Munk, Prof Bruce Forster and Prof Hugue Ouellette, the fellowship centred on advanced musculoskeletal imaging, sports imaging and musculoskeletal interventions. Upon his return to Singapore and during his tenure as Consultant at Tan Tock Seng Hospital, he started several interventional programmes for tumour ablations (for both palliative and benign), vertebroplasties, hydrodilatation clinics for adhesive capsulitis and other musculoskeletal ultrasound-guided procedures. |

Introduction
Consultant Radiologist Clinical Interest & Subspecialty: Neuroradiology (Brain, Head & Neck, Spine) and Neurointervention Dr Santhosh Raj is a Consultant Radiologist with 20 years of experience in radiology. He graduated from Universiti Sains Malaysia in 2002 and obtained the Fellowship of the Royal College of Radiologists (U.K.) in 2008. Upon completing the Advanced Specialist Training (AST) in Singapore in 2013, he joined the Neuroradiology subspecialty team at Singapore General Hospital. In 2015, he completed his training in Neurointervention at the National Institute of Clinical Neurosciences in Budapest, Hungary, through the SingHealth Health Manpower Development Program (HMDP) fellowship. In addition to his routine work, Dr Santhosh also reports MRI Brain Volumetry scans that are used to assess structural brain degeneration, particularly Alzheimer’s disease and related dementias (ADRD). He also reports Ultra Low-Dose (Submilisievert) CT Lung, which allows lung screening at doses lower than routine lung screening CT scans. Other innovative imaging scans that he developed in the past include Intracranial Vessel Wall Imaging (3T MRI), an optimized CT Arterio-Venography (CTAV) of the brain, and an optimized Multiphasic CT Angiography of the Neck and Brain (acute stroke management). His past appointments include Deputy Director of Vascular and Interventional Radiology (SGH), and Director of Radiology Training (SGH). He was also Clinical Lecturer at the Yong Loo Lin School of Medicine (NUS), and Adjunct Assistant Professor at Duke NUS. Dr Santhosh is particularly interested in imaging informatics and artificial intelligence (AI). He is passionate about teaching and developing innovative imaging scans. He also loves to walk and spend quality time with his family. |
