In general, 6 to 8 hours without food help the liver and gallbladder be seen more clearly. You may drink water, and you usually take your regular medicines with a sip of water.

A full bladder moves the bowel away and works like a window to see the uterus and ovaries. Drink water beforehand and hold your urine. For transvaginal ultrasound, it is the opposite: the bladder should be empty.

No fasting and no full bladder are needed. Avoid necklaces and high collars because the exam is done on the neck. It is quick and painless.

No fasting. On the day, avoid cream, talc, or deodorant on the area. If you have prior exams, bring them: comparison helps.

It depends on the stage. Early in pregnancy, a full bladder may be requested; later, usually not. Follow your clinic instructions and bring your prenatal exams.

A full bladder is often requested: drink water beforehand and hold your urine so the bladder and emptying can be assessed. Fasting is usually not necessary.

Usually no preparation is needed. Wear comfortable clothes that uncover the leg easily. The exam checks circulation and is not painful.

Before: do I need preparation? can I take my medicines? After: when will the report be ready and who will explain the result? Writing down questions beforehand helps a lot.

A nodule does not mean cancer — most are benign. The report often includes a category, such as TI-RADS or BI-RADS, to guide whether follow-up or investigation is needed. Your doctor decides the next step.

It is a 1-to-5 scale that organizes thyroid nodule features and suggests when puncture may be useful. A higher number means more attention, but only your doctor can define management after seeing the whole picture.

It is the classification of breast findings from 0 to 6. Categories 1 and 2 are reassuring; from 3 onward, follow-up or evaluation may be needed. The number guides care; it is not a final diagnosis by itself.

The report describes the gland size, texture, and nodules. Terms like echogenicity and margins are image features. The most important summary is usually in the conclusion.

A cyst is a small fluid-filled sac — almost always benign and common in the kidney, liver, breast, and ovary. The report says whether it is simple and reassuring or deserves follow-up.

It means something found along the way, unrelated to the reason for the exam. Often it is not important, but the report may suggest confirming it with your doctor for peace of mind.

Gallstones are very common and do not always cause symptoms. When they cause pain, especially after fatty meals, treatment should be discussed. Ultrasound shows size and number well.

Fatty liver means fat accumulated in the liver — it is common and, early on, reversible. It often improves with diet, physical activity, weight control, and glucose control. Your doctor assesses the grade and follow-up.

A fibroid is a benign nodule of the uterus and is very common. Many cause no symptoms and are only followed; others may need treatment depending on size and symptoms. Ultrasound measures and locates each one.

Most ovarian cysts are functional and disappear on their own over a few cycles. Ultrasound describes the type, and your doctor decides whether to repeat the exam or investigate further.

Thyroid nodules are very common and almost always benign. The report uses TI-RADS to guide follow-up or puncture. Most only need periodic monitoring.

A lump in the neck is often a lymph node reacting to an infection and improves on its own. Ultrasound helps differentiate. Seek evaluation if it grows, feels hard, or does not go away.

Evaluates gland size and looks for nodules. It is quick, painless, and uses no radiation. Most findings are benign and only need follow-up.

Evaluates the liver, gallbladder, bile ducts, pancreas, spleen, and kidneys. Fasting is often requested, and it is a first-line exam for many abdominal pains.

Complements mammography, especially in dense breasts and younger women. It helps distinguish cysts from solid nodules, without radiation.

Evaluates the kidneys, bladder, and urine emptying. It helps investigate stones, cysts, and difficulty urinating. A full bladder is often requested.

Measures prostate volume and evaluates the bladder and urine left after voiding. It may be abdominal, with a full bladder, or transrectal, depending on your doctor’s indication.

Follows the baby at each stage — from confirming pregnancy to growth and well-being. See what each exam evaluates trimester by trimester.

Usually when there is a palpable nodule, altered thyroid hormones, or to follow known nodules. Your doctor defines the interval for your case.

To investigate a finding, complement mammography in dense breasts, or evaluate younger women. Frequency depends on your history and medical guidance.

It is indicated for abdominal pain, suspected gallstones, liver test changes, or as routine when requested by your doctor.

It often becomes part of evaluation after age 50, or earlier with family history, or when urinary symptoms are present. Talk with your doctor about the best timing.

It is usually between 6 and 8 weeks to confirm pregnancy. Start prenatal care as soon as you know — then follow a trimester calendar.

Many benign findings only need follow-up: the report or your doctor will indicate when to repeat it. Keep previous exams for comparison.
