[Computed tomographic colonography].

Duodecim; laaketieteellinen aikakauskirja, 2014
Computed tomographic colonography, i.e. CT colonography has already widely replaced double-contrast colonography as a method of examination of the colon. A prerequisite of successful examination is a well-emptied and distended colon. CT colonography detects cancer with a sensitivity of 96%, which corresponds to the results of colonoscopy.

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.

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.

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

Appendiceal diverticulosis incidentally detected by computed tomographic colonography

Digestive and Liver Disease, 2016
A 63-year-old man with diabetes mellitus, hypertension, nd hyperlipidemia, who had been followed up regularly for 9 years, visited our hospital for positive findings on fecal mmunochemical screening test. Although he had no abdominal ymptoms, computed tomographic colonography (CTC) was perormed for colorectal cancer screening. Colorectal neoplasms were

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.

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

Is Computed Tomographic Colonography Being Held to a Higher Standard?

Annals of Internal Medicine, 2010
Recent guidelines for colorectal cancer screening have reached different conclusions on whether computed tomographic colonography (CTC) is an acceptable screening option, and the Centers for Medicare & Medicaid Services recently decided not to cover CTC screening.

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: 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.
