Computed tomography (CT)-detected lung nodules remain a challenge in clinical practice. This is due to the difficulty in distinguishing between their varying etiologies: infection, primary lung cancer, metastasis, or hamartoma to name a few. Lung nodules are identified on 15 to 30% of all comput...
The detailed COVID-Facts's structure and methodology is explained in detail at https://arxiv.org/abs/2010.16041 . Note : Please don’t use COVID-FACT as the self-diagnostic model without performing a clinical study and consulting with a medical specialist. COVID-FACT is not a replacement ...
All participants will provide written informed consent before randomisation after the objectives and methodology of the trial have been explained to them in detail by the investigators. Participants have the right to withdraw from the trial at any time without giving a reason and will not be ...
Cranial CT: Normal Findings The scan usually begins at the base of the skull and continues upward. Since the hard copies are oriented such that the sections are viewed from caudal, all structures appear as if they were left/right reversed (see p. 14). Th
After a CT scan in 2001 had led to middle-of-the-night surgery, doctors determined the ten-year-old’s mass was a deadly tumor(肿瘤). Though they removed it, the tumor came back the next year, requiring another surgery, and the year after, when it had become horribly involved with...
Slip ring systems in CT scanners make it possible to scan in quick succession with scan times less than one second. The sensitivity to motion artifacts is low, even when higher dose is required, because images can be produced with more than one rotation. The principles and advantages of this...
, 2006; Berrington de González, 2009; Berrington de Gonzalez et al., 2012) and are explained in detail in the supplementary web material. A dose and dose-rate effectiveness factor (DDREF), modelled by a lognormal distribution with a geometric mean of 1.5 and a geometric standard deviation ...
This study aims to decrease the scan time and enhance image quality in pediatric total-body PET imaging by utilizing multimodal artificial intelligence techniques. A total of 270 pediatric patients who underwent total-body PET/CT scans with a uEXPLORER a
If you are planning on using the democratiz3D service to automatically convert a medical scan to a 3D printable STL model, or you just happen to be working with medical scans for another reason, it is important to know if you are working with a CT (Compu
Temporal bone CT-scan is a prerequisite in most surgical procedures concerning the ear such as cochlear implants. The 3D vision of inner ear structures is crucial for diagnostic and surgical preplanning purposes. Since clinical CT-scans are acquired at r
