What the Equipment on This Site Actually Checks For

These four often get lumped together as "scans," but they're built for different jobs. MRI uses magnets rather than radiation and is the standard choice for soft tissue — torn ligaments and cartilage (an ACL or a meniscus tear, for example), herniated spinal discs, and brain abnormalities including stroke damage or tumors. It's slower and typically the more expensive of the two cross-sectional scans, but it sees soft tissue detail that a CT can't.

CT (computed tomography) is a fast, cross-sectional X-ray. It's usually the first choice after trauma — internal bleeding, organ injury, complex fractures — and it's also standard for kidney stones and lung nodules. Where MRI is chosen for tissue detail, CT is usually chosen for speed and bone/structural detail.

Plain X-ray is the oldest and cheapest of the three, and still the right first step for a straightforward fracture, joint arthritis, or a basic chest check for pneumonia. Clinics don't reach for MRI or CT unless the X-ray doesn't answer the question.

Ultrasound uses sound waves, not radiation, and works in real time. It's the standard tool for the gallbladder, liver, and kidneys, for abdominal pain of unclear cause, and — with Doppler ultrasound specifically — for checking blood flow through vessels. A thyroid ultrasound is the same technology aimed at the thyroid gland, used to check nodules or an enlarged thyroid (goiter), and sometimes to guide a needle biopsy of a suspicious growth.

An ECG (electrocardiogram) records the heart's electrical activity from the skin — it's quick, painless, and the standard first test for an irregular heartbeat, chest pain of unclear cause, or signs of a past or current heart attack.

EMG and nerve conduction studies do the equivalent for nerves and muscles, measuring electrical signals to find where a nerve is compressed or damaged. This is the test behind a carpal tunnel syndrome diagnosis, a pinched nerve in the neck or back, or peripheral neuropathy (nerve damage that often shows up as numbness or tingling in the hands or feet).

A bone density scan is a low-dose scan built specifically to measure bone mineral density — it's the standard test for osteoporosis and osteopenia, and for tracking fracture risk over time rather than diagnosing a single injury.

Spirometry measures how much air you can breathe out and how fast. It's the standard test for diagnosing and monitoring asthma and COPD, and for working out unexplained shortness of breath.

Endoscopy, in the context of the ENT clinics on this site, means a thin camera scope used to directly examine the nose, throat, or larynx — used for chronic sinusitis, nasal polyps, vocal cord lesions, or throat symptoms that don't have an obvious cause from an external exam alone.

Audiometry (a hearing test) measures your hearing threshold across different sound frequencies — it doesn't just confirm hearing loss, it maps out which frequencies are affected, which is what actually guides treatment.

The equipment badges on clinic profiles link a specific piece of confirmed equipment to what it's actually for — so "MRI" on a listing means more than a generic sense of "advanced technology." If you already know roughly what kind of test your situation calls for, you can use the network page's filters to find clinics that have confirmed that specific capability, rather than guessing from a clinic's general reputation.
