Results:Of the 26 722 NLST participants, 422 (1.6%) had enlarged noncalcified mediastinal lymph nodes on the initial LCS CT scan. Mediastinal lymphadenopathy was associated with an increase in lung cancer cases (72 of ...

The CT dose indices were 0.68, 1.7, 3.4, 5.2, 6.8, and 11.9 mGy. Each cadaveric lung was scanned in one slice at three different position levels. So we acquired three images per cadaveric lung. Scan mode was helical scan and acquired CT images were axial image. All CT images with ...
This research finding indicates that X-ray datasets are preferred for detecting pneumonia, while CT scan datasets are predominantly favored for detecting lung cancer. Furthermore, in COVID-19 detection, X-ray datasets are prioritized over CT scan datasets. The analysis reveals that X-rays and CT...
a–d Axial CT images (a–d) without contrast (slice thickness of 1 mm) of an 81-year-old gentleman show traction bronchiectases (white circles) and subtle cystic airspaces (black arrows), compatible with subpleural fibrotic ILA. (d) The CT scan, performed following the depiction of a ...
CT scan of the chest and abdomen: An X-ray machine linked to a computer takes a series of detailed pictures of areas inside the body from different angles. The doctor may inject a dye into a vein. They may have you take a substance called a contrast agent by mouth. It helps your org...

before PET acquisition, the non-contrast low-dose CT portion of CT scan was performed from the base of skull to the mid-thigh of the patient in the same treatment supine position on a radiolucent operation table for attenuation correction. After injection of 18 F-FDG tracer for 60 min, ...
The patient performed a contrast CT scan on the same day, thus, iobitridol was injected between 99mTc-HDP intravenous injection and bone scan images acquisition. Fine helical slices showed no abnormality and especially no nodule or micronodule in the left lung. In order not to miss out a ...
2.2. CT Examination Protocol Thin-section non-contrast CT images were obtained during inspiration with the patient in a supine position using 320- or 64-row multi-detector CT scanners (Aquilion ONE GENESIS or Aquilion 64, Canon Medical Systems, Otawara, Japan). The scanning parameters were 0.5-...
