  2. High-resolution computed tomography - Wikipedia

    en.wikipedia.org/wiki/High-resolution_computed...

    Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...

    Modern detail-oriented scans such as high-resolution computed tomography (HRCT) is the gold standard in respiratory medicine and thoracic surgery for investigating disorders of the lung parenchyma . Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses , as well as to assess lymph node status at ...

    Douglas Boyd, PhD and Harry Genant, MD used a CT head scanner to do some of the seminal work on QCT. [3] At the same time, CT imaging technology progressed rapidly and Genant and Boyd worked with one of EMI's first whole body CT systems in the late 1970s and early 1980s to apply the quantitative CT method to the spine, coining the term "QCT."

  5. CT scan - Wikipedia

    en.wikipedia.org/wiki/CT_scan

    Dual source CT is an advanced scanner with a two X-ray tube detector system, unlike conventional single tube systems. [15] [16] These two detector systems are mounted on a single gantry at 90° in the same plane. [17] Dual Source CT scanners allow fast scanning with higher temporal resolution by acquiring a full CT slice in only half a rotation.

  6. Mammography - Wikipedia

    Those with a history of chest radiation therapy before age 30 should start annually at age 25 of 8 years after their latest therapy (whichever is latest). [38] The American Cancer Society also recommends women at high risk should get a mammogram and breast MRI every year beginning at age 30 or an age recommended by their healthcare provider. [36]

    All women who undergo breast cancer screening with a mammogram in the U.S. must now find out if they have dense breasts — a risk factor for developing breast cancer.. Starting Tuesday, Sept. 10 ...

  8. Breast imaging - Wikipedia

    en.wikipedia.org/wiki/Breast_imaging

    Breast MRI is a technology typically reserved for high-risk patients and patients recently diagnosed with breast cancer. [3] Lastly, scintimammography is used in a subgroup of patients who have abnormal mammograms or whose screening is not reliable on the basis of using traditional mammography or ultrasound.

  9. Contrast CT - Wikipedia

    en.wikipedia.org/wiki/Contrast_CT

    Bolus tracking is a technique to optimize timing of the imaging. A small bolus of radio-opaque contrast media is injected into a patient via a peripheral intravenous cannula . Depending on the vessel being imaged, the volume of contrast is tracked using a region of interest (abbreviated "R.O.I.") at a certain level and then followed by the CT ...
