CT – Scan

Brought to you by Healthbase

CT (Computed Tomography) is a diagnostic test that combines the use of x-rays with computer technology. A series of x-rays beams from different angles around the body are used to show cross sectional images of the patient’s body. The images so obtained are assembled in a computer into a three- dimensional picture that can display organs, bones & tissues in great detail.

In spiral CT the examination table advances at a constant rate through the scanner gantry. While the x-ray tube rotates continuously around the patient, tracing a spiral path through the patient. This spiral path gathers continuous data with no gaps between images.

CT Angiography (CTA) is an examination that is used to visualize blood vessels in many areas of the body including the brain, kidneys, pelvis and the arteries serving the lungs. Compared to catheter angiography, which involves injecting contrast medium into an artery CTA is much less invasive & a more patient friendly procedure; contrast medium is injected into a vein rather than an artery.

Why is it done?
CT imaging offers detailed views of different types of tissue, including the lung, bones, soft tissues and blood vessels Using specialized equipment & expert technician to create CT scans of the body , radiologists can more easily diagnose problems such as cancers, cardiovascular diseases ,infectious diseases, trauma & musculoskeletal disorders.

How is it done?
Patient is asked to change into a gown before the examination & to remove jewellery, eyeglasses and metal objects depending on the part of the body that is being scanned.

The CT technician begins by positioning the patient on the CT table. The patient’s body is supported by the safety straps & is asked to lie very still and follow the instructions of the technician while the scanning is being performed. During the scanning, the technician can see, hear & speak to the patient at all times.

A CT examination often requires the use of different contrast agents to enhance the visibility of certain tissues or blood vessels. The contrast agent may be injected directly into the blood stream, swallowed or administered by enema, depending on the type of examination. Before administering the contrast agent the radiologist or technician will ask whether the patient has any allergies, especially to medications, iodine and whether the patient has a history of diabetes, asthma, a heart condition, kidney problem or thyroid conditions as these conditions indicate a higher risk of reaction to the contrast agent. Fortunately with the safety of the newest contrast agents the adverse effects are very rare.

The department of Radiodiagnosis & Imaging at EHIRC is well equipped to deal any emergency. A CT examination usually takes from 15 minutes to half an hour. When the exam is over, the patient may be asked to wait until the images are examined to determine if more images are needed.

For the CT Angiography contrast medium is injected into a vein with an automatic injector machine that controls the timing & rate of injection, which may continue during part of the time images are recorded. Afterwards the images are reviewed & some will be repeated, if necessary. The real work of CT angiography comes after the images are acquired, when powerful computer programs process the images & make it possible to display them in different ways.

When it is done/advised ?
It is done when clinicians prescribe it after examining patient and going through his/her records. The radiologists also advise for CT scan when routine x-rays and ultrasonography fail to provide adequate information. It is better device for interventional procedures.

Eat Smart

By Ms Melissa Aiyathurai-Johnston
Dietitian, Raffles Hospital

Food, food, glorious food! Food makes up a big part of our life. Besides providing nutritional benefits, food is also a source of enjoyment, an adventure and it tastes great!

Despite huge and beneficial gains in knowledge about nutrition over recent years, healthy eating has become harder because of the way we live and eat today. There is less reliance on home cooked meals and if we are not mindful, our meals may not be necessarily healthy. They may not be complete (e.g. not being served with enough vegetables) or the portion sizes may be too large.

In addition, the modern diet is usually overloaded with calories for energy compared to the amount we expend, has too much fat (especially saturated fat), sugar and salt and lacking in fruits, vegetables, fibre and dairy products.

This state of “over nutrition” has seen an alarming rise in the incidence of chronic lifestyle diseases. Today 1 out of 3 Singaporeans are overweight or obese which sets the scene for other conditions such as diabetes and heart disease. Excessive fat or salt and the lack of fibre have also been linked with an increase risk of certain cancers (e.g. breast, bowel, stomach), diabetes, stroke, hypertension and osteoporosis to name a few.

There is no secret to healthy eating. You just need to “eat smart”!

Enjoy a wide variety of foods
Add the grains and legumes
Trim the fat

Shake the habit – reduce your salt intake
Munch those fruits and vegetables
Alcohol – enjoy in moderation
Reduce your sugar intake
Track your weight

Enjoy a wide variety of foods
Variety is the spice of life! Everyday your body needs nutrients and other healthful substances (such as antioxidants) that only a wide variety of foods can provide. Most foods and beverages are made up of more than one nutrient, however no one food or food category has them all.

Add grains and legumes
These low fat foods should make up a large proportion of your meals. This group including bread, cereals, rice, pasta and other foods made from grains provides you with carbohydrate (your body’s fuel), B vitamins, fibre and a number of minerals. Legumes (e.g. peas, beans and lentils) provide you with good amounts of protein (important for vegetarians), B vitamins and fibre.

Having more soluble fibre in your diet, such as the type found in legumes will help to lower your cholesterol. The slow digesting carbohydrate they contain will also help those trying to control their weight or diabetics with their blood sugar control.

Trim the fat
Reducing your fat intake will lower your risk of becoming overweight which reduces your chance of certain conditions such as diabetes, heart disease, hypertension and certain cancers. Reducing your saturated fat intake will also go a long way to help keep your cholesterol in check.

Removing the skin from poultry and limit your intake of fatty meat such as pork belly, luncheon meat. When dining away from home choose more soup based dishes which are low in fat and limit those dishes made with coconut milk.

Shake the habit – reduce your salt intake
Too much salt has been linked to the development of high blood pressure or hypertension. The average diet contains more sodium than actually required.

One way to reduce your sodium intake is by tasting your food before adding salt. Also limit or avoid high sodium condiments such as soy sauce, oyster sauce, tomato ketchup. Opt for herbs, spices, chili or lime juice to add flavour instead.

Munch those fruit and vegetables
Besides being an excellent source of fibre, this low calorie, nutrient dense group provides you with essential vitamins and minerals, antioxidants, and phytochemicals that may not be present in other groups of food. Studies have shown that those people with a high intake of fruits and vegetables have a low rate of heart disease and cancer. Aim for 2 servings of fruit and vegetables daily.

Alcohol – enjoy in moderation
A moderate to heavy intake of alcohol has been associated with high blood pressure and certain cancers. An excessive intake can also lead to weight gain as gram for gram alcohol has almost twice the calories of carbohydrate or protein.

A safe intake would be no more than 2 standard drinks a day for women and no more than 4 for men with 2 alcohol free days per week.

Reduce the sugar intake
Food high in sugar tend to be “empty calories” as they have no essential fibre, vitamins or minerals and can sometimes displace more nutritious food. Most foods high in sugar also tend to also be high in fat, which if taken in excess can lead to weight gain. It is best to enjoy these foods in moderation.

Track your weight
A balance between the right food and regular exercise will ensure that your weight is healthy. Choosing low fat meals with ample carbohydrates, vegetables, fruit and protein will help you lose excessive weight, if you need to and help you to stay slim if you do not.

Be careful of fad diets or diets that offer fast weight loss as they more often do not change your eating habits and are nutritionally unbalanced. Once you go off them, the weight tends to come back straight away.

 Photoaging

(Source: Raffles Hospital)

Do You Know About Photoaging?

Skin aging becomes a prominent issue as the “baby boomers” and “late baby boomers” enter their 50s and 40s respectively. Everybody desires not only to look younger, but young too. Thus new anti-aging products and devices appear overnight in this multi-billion dollar industry. The barrage of information that comes through the media and Internet often misleads rather than educate the public. It is important therefore to know what works and what does not.

What is photoaging?
Skin aging has two components: intrinsic aging and photoaging. Intrinsic aging of skin occurs as a natural part of the aging process. However photoaging occurs as a result of ultraviolet light from sun exposure. Signs of photoaging including wrinkling, sagging, roughness, loss of luster, and age spots. Excesive exposure to the sun can also cause precancerous lesions such as solar keratosis, and cancerous lesions such as squamous cell carcinoma and melanoma.

Can photoaging be avoided?
Firstly, sunscreen should be started right away. Most people deny that they are sun-exposed and think that they are spread. A walk in the park during the day, hanging out the clothes, working by an unshielded window or a long car-ride are examples of activities that are easily overlooked. Some practical advice with regards to sun protection include the following:

  • Stay out of the sun between 9 am and 4 pm as much as possible.
  • Adequate covering for the arms and legs when outdoor, and a wide-brimmed hat for the face and scalp.
  • Daily use of an appropriate sunscreen with a SPF of 20 or more.

These are various treatments available for photoaging.

  1. Sunscreen
  2. Moisturiser
  3. Tretinoin Cream
  4. AHA (Alpha-hydroxy acids) cream
  5. Antioxidants
  6. Chemical peel
  7. Soft tissue augmentation
  8. Botox injection
  9. Dermabrasion
  10. Laser resurfacing
  11. Non-invasive method
