Radiology and Imaging in Sharjah

What radiology is, and who the radiologist is

Radiology produces and interprets medical images. It is how a doctor sees inside you without an incision, and it underpins decisions made in almost every other department.

Most patients never meet the person who matters most in the process. A radiographer performs your scan. A radiologist is a doctor who specialises in interpreting the images and writes the report your treating doctor acts on.

That report is a medical opinion, not an automated output. A well-reported scan answers the clinical question, flags what is relevant, and says plainly what remains uncertain. A poorly reported one lists findings without interpretation and leaves everyone none the wiser.

How to get a scan here

Imaging is arranged by a doctor, not requested directly. Your consultation determines which examination will actually answer the question — the wrong scan gives a confident answer to a question nobody asked.

If you have been referred from outside the hospital, bring the referral and any previous imaging.

Bring previous scans, however old. This is the single most useful thing a patient can do in radiology. Comparison with earlier imaging frequently settles a question that a new scan alone cannot — a nodule unchanged over two years, a disc bulge present before the current symptoms, a cyst the same size as last year. Without the comparison, the answer is often "further imaging recommended."

The examinations

X-ray. Fast, widely available, low radiation dose. Best for bone — fractures, joints, alignment — and for a first look at the chest. It shows dense structures well and soft tissue poorly.

Ultrasound. No radiation at all, uses sound waves. The first choice for the abdomen, liver, gallbladder, kidneys, thyroid, testes, soft-tissue lumps and every obstetric scan. It is operator-dependent — the quality of an ultrasound reflects the skill of the person performing it more than any other modality.

Doppler ultrasound adds blood flow assessment, used for suspected clots and for arterial and venous disease.

CT. Rapid, detailed cross-sectional imaging. The investigation of choice for acute abdominal pain, significant trauma, suspected stroke, and detailed chest and bone assessment. It uses ionising radiation, which is why it is used where it changes the decision rather than routinely.

MRI. No ionising radiation, uses a strong magnetic field. Unmatched for soft tissue — brain, spinal cord, discs, ligaments, cartilage, muscles and many abdominal organs. Slower and noisier than CT, and unsuitable for some patients with metallic implants.

Mammography. Dedicated breast imaging for screening and for assessment of breast symptoms, often alongside ultrasound.

Bone density (DEXA). Measures bone mineral density for osteoporosis assessment. Low dose, quick, painless.

Image-guided procedures. Ultrasound or CT guidance for biopsies, drainage and targeted injections, allowing precision without open surgery.

About radiation — the honest answer

Patients ask about this constantly and are usually given reassurance rather than information.

Ultrasound and MRI use no ionising radiation at all. X-ray uses a small dose. CT uses considerably more than an X-ray, though modern equipment and protocols have reduced doses substantially.

The principle applied is that an examination should be done when the information it provides outweighs the small risk, and not otherwise. This is why your doctor may decline a scan you have asked for, and why the alternative — ultrasound or MRI — is preferred where it answers the same question.

Tell the team before any examination if you are pregnant or might be. For most imaging in pregnancy, ultrasound or MRI is used instead.

Preparing for your scan

Preparation varies, and getting it wrong means a repeat visit.

Abdominal ultrasound usually requires fasting for several hours, so the gallbladder is distended and bowel gas reduced. Pelvic ultrasound often requires a full bladder. CT with contrast requires fasting and, in some cases, a recent kidney function blood test. MRI requires removing all metal, and you must tell the team about a pacemaker, implants, surgical clips, metal fragments in the eye, or a cochlear implant. Mammography is usually scheduled avoiding the week before a period, when breasts are more tender.

You will be given specific instructions when your appointment is arranged. Follow them exactly — most repeat appointments in radiology are caused by preparation, not by the equipment.

What the scan itself is like

X-ray takes seconds. Ultrasound takes 15 to 30 minutes; gel is applied and a probe moved over the skin, and it is painless.

CT takes minutes. You lie on a table that moves through a ring — open at both ends, so it rarely troubles people who dislike enclosed spaces. Contrast, if used, is injected and commonly produces a brief warm sensation.

MRI takes 20 to 60 minutes depending on the study. It is loud — you will be given ear protection — and you must stay still, because movement blurs the images and may require repeating the sequence. The tunnel is more enclosed than CT. If you are claustrophobic, say so when booking rather than on the day; it can be planned for.

Getting your results

Images are reviewed and reported by a radiologist, and urgent findings are communicated to the referring doctor immediately. Results timing depends on the test. Your doctor will tell you when to expect yours.

The report goes to your doctor, and it is meant to be read alongside your clinical picture. Reading a radiology report alone, without that context, is how people frighten themselves over findings that are common, age-related and irrelevant to their symptoms — degenerative changes, small cysts, minor disc bulges. These terms sound alarming and are usually normal.

Discuss the result with the doctor who ordered it.

Second-opinion review

Where you have imaging from elsewhere, our radiologists can review the original images and provide an independent report. Bring the images themselves, on disc or file — a report is one radiologist's interpretation, and a genuine second opinion requires looking at the study.

Cost and insurance

Most UAE plans cover X-ray and ultrasound. CT and MRI almost always require pre-approval, which is a common source of delay — start it as soon as the scan is requested. Screening examinations without symptoms are sometimes excluded even where diagnostic imaging is covered. Confirm on 06 599 7777.
