How do they detect asbestos in a laboratory? Analysis involves breaking apart the submitted sample, locating fibres under stereomicroscope, then isolating and identifying the fibres. The isolated fibres are identified utilizing polarized light microscopy (PLM), including dispersion staining (DS).
Can breast MRI detect microcalcifications? Conclusion. Breast MRI can accurately distinguish between benign and malignant microcalcifications and may thus be helpful to reduce unnecessary breast biopsies. In this respect, breast MRI may be particularly helpful in microcalcifications with a low likelihood of malignancy.
When should you get an MRI for a headache? While many people with migraine don’t need an MRI, your doctor might recommend it if you have any headache red flags. These are sudden changes in headache patterns or certain signs that there may be a more serious underlying problem, including: Increase in frequency or changes in the intensity of headache.
What kind of MRI is used for headaches? If a scan is ordered to evaluate a headache disorder, MRI with contrast is preferred as it is a more sensitive test than CT and does not involve any radiation. However, as it is so sensitive, there are often abnormal findings unrelated to the headache that may lead to further testing.

What does a bone density test detect?
A bone density test determines if you have osteoporosis — a disorder characterized by bones that are more fragile and more likely to break. The test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone.
Can cbc detect hepatitis?
A complete blood count (CBC) is one of the most commonly performed blood tests. Since it reveals peripheral blood changes, the CBC is routinely performed in health examinations, even in asymptomatic patients. However, there is no evaluation showing the screen for HCV potential infection by CBC data.
Can telescopes detect high energy quasars?
With high-resolution imaging from ground-based telescopes and the Hubble Space Telescope, the “host galaxies” surrounding the quasars have been detected in some cases. These galaxies are normally too dim to be seen against the glare of the quasar, except with special techniques.

Iodine is made into two radioactive isotopes, I-123 and I-131, that are commonly used in patients with thyroid disease.
Is a blood test the fastest way to detect hiv?
An antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after an exposure. Antigen/ antibody tests done with blood from a finger prick can take longer to detect HIV (18 to 90 days after an exposure).
Does hepatitis show up in blood tests?

Both the core and jets are visible with radio telescopes while only the core is usually visible with optical telescopes. Even though quasars are intrinsically very bright, we cannot see any quasars in the night sky without using a telescope. This is because the nearest quasars are more than a billion parsecs away.
