Partial preparation computed tomographic colonography: a feasibility study

Abdominal Imaging, 2011
We retrospectively evaluated computed tomographic colonography examinations of patients who have had a partial bowel preparation and compared the quality of their preparation with patients who have had a full bowel preparation. In total, 27 patients undergoing computed tomographic colonography examination (10 patients with partial bowel preparation and

Three-dimensional computed tomographic angiography with computed tomographic colonography for laparoscopic colorectal surgery

Japanese Journal of Radiology, 2018
To prospectively correlate the preoperative vessel anatomy in three-dimensional computed tomographic angiography with computed tomographic colonography (3D-CTA with CTC) with that in laparoscopic surgery for colorectal cancer.The study protocol was approved by our institutional review board.

Computer-Aided Diagnosis in Computed Tomographic Colonography

2010
Computed tomographic colonography (CTC) is gaining acceptance as a method to screen the colon and rectum for polyps and masses, but there is a substantial learning curve [1, 2] and sensitivity remains variable [3]. Computer-aided diagnosis (CAD) has recently been referred to more often as “computer aided detection” and abbreviated CADe as distinct from

CAD techniques, challenges, andcontroversies in computed tomographic colonography

Abdominal Imaging, 2004
Computer-aided diagnosis (CAD) for computed tomographic colonography (CTC) automatically detects the locations of suspicious polyps and masses on CTC and provides radiologists with a second opinion. CAD has the potential to increase radiologists' diagnostic performance in the detection of polyps and masses and to decrease variability of the diagnostic ...

Computed Tomographic Colonography: Image Display Methods

2010
High reader performance (high sensitivity levels with low false-positive rates) and time efficiency are the two main goals sought during interpretation of computed tomographic colonography (CTC) examinations. As CTC continues to grow as a valid screening test for colorectal neoplasia, one concern is that, as currently proposed by most authorities in ...

Computed Tomographic Colonography: Current Perspectives and Future Directions

Gastroenterology, 2009
Computed tomographic (CT) colonography, also known as virtual colonoscopy or CT colography, is capable of detecting colon polyps and cancers. It is emerging rapidly and has gained great momentum over the past several years, to the point where it has been proposed to be a viable primary colon cancer screening option.

The future of colorectal imaging: computed tomographic colonography

Gastroenterology Clinics of North America, 2002
The development of colorectal cancer screening alternatives that are attractive to patients and effective for screening is critical for reducing this too-common and deadly disease. CTC is an exciting technique that is the only imaging alternative developed since the barium enema for colon screening.

Economic Impact of Extracolonic Findings at Computed Tomographic Colonography

Journal of Computer Assisted Tomography, 2008
To determine the prevalence of extracolonic findings at computed tomographic colonography (CTC) and estimate the cost of the workup of newly discovered potentially significant lesions.An electronic information system was used to review all patient data before and after the CTC in a mixed cohort of 376 patients.

[Computed tomographic colonography: applications, advantages and disadvantages].

Gastroenterologia y hepatologia, 2005
Complete preoperative study of the colon is required in the management of colorectal cancer, due to the frequent association of primary colonic neoplasms with colonic adenomas (28%) and/or synchronous carcinomas (5%) of the colon. We present a series of patients who underwent computed tomographic colonography, the indications for this procedure, and ...

Can Computed Tomographic Colonography Become a “Good” Screening Test?

Annals of Internal Medicine, 2005
When prepless computed tomographic colonography achieves a reasonably high and consistent sensitivity for an appropriate target lesion, we may finally have a good screening test.
