    Lesion specific calcium score. The Agatston score, named after its developer Arthur Agatston, is a measure of calcium on a coronary CT calcium scan. [7] The original work, published in 1990, [8] was based on electron beam computed tomography (also known as ultrafast CT or EBCT). The score is calculated using a weighted value assigned to the ...

    en.wikipedia.org/wiki/Hypercalcaemia

    Calcium deposits known as limbus sign may be visible in the eyes. [7] Symptoms are more common at high calcium blood values (12.0 mg/dL or 3 mmol/L). [6] Severe hypercalcaemia (above 15–16 mg/dL or 3.75–4 mmol/L) is considered a medical emergency: at these levels, coma and cardiac arrest can result.

  4. Hypercalciuria - Wikipedia

    The gold standard to assess for hypercalciuria is 24-hour urine collection to evaluate urine calcium levels over that time period. Normal range is considered 100 to 300 milligrams per day (mg/day) with standard calcium intake. Hypercalciuria is diagnosed when a value over 300 mg/day is identified. [6]

  5. Coronary CT angiography - Wikipedia

    Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.

    Primary hyperparathyroidism affects approximately 1 per 1,000 people (0.1%), [20] while there are 25–30 new cases per 100,000 people per year in the United States. [21] The prevalence of primary hyperparathyroidism has been estimated to be 3 in 1000 in the general population and as high as 21 in 1000 in postmenopausal women. [22]

  9. Disorders of calcium metabolism - Wikipedia

    en.wikipedia.org/wiki/Disorders_of_calcium...

    Disorders of calcium metabolism occur when the body has too little or too much calcium. The serum level of calcium is closely regulated within a fairly limited range in the human body. In a healthy physiology, extracellular calcium levels are maintained within a tight range through the actions of parathyroid hormone , vitamin D and the calcium ...
