  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 ...

  3. Computed tomography of the chest - Wikipedia

    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 ...

    The laminographic imaging technique dates back to the 1930s and belongs to the category of geometric or linear tomography. [17] Because the data acquired are very high resolution (85–160 micron typical), much higher than CT, DBT is unable to offer the narrow slice widths that CT offers (typically 1–1.5 mm).

    Drawing of CT fan beam and patient in a CT imaging system CT scan of the thorax. The axial slice (right) is the image that corresponds to number 2/33 on the coronal slice (left). Spinning tube, commonly called spiral CT, or helical CT, is an imaging technique in which an entire X-ray tube is spun around the central axis of the area being ...

  7. Tomosynthesis - Wikipedia

    en.wikipedia.org/wiki/Tomosynthesis

    Tomosynthesis, also digital tomosynthesis (DTS), is a method for performing high-resolution limited-angle tomography at radiation dose levels comparable with projectional radiography. It has been studied for a variety of clinical applications, including vascular imaging, dental imaging, orthopedic imaging, mammographic imaging, musculoskeletal ...

  8. Mammography - Wikipedia

    en.wikipedia.org/wiki/Mammography

    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]

  9. Computed tomography laser mammography - Wikipedia

    en.wikipedia.org/wiki/Computed_Tomography_Laser...

    The sensitivity of mammography, CTLM and mammography + CTLM was 34.4%, 74.4% and 81.57% respectively among extremely dense breasts and 68.29%, 85.00% and 95.34% respectively among heterogeneously dense breasts. [12] The combination of CTLM and mammography is able to distinguish between benign and malignant tumors with higher accuracy.
