Is Iterative Reconstruction Ready for MDCT? [PDF]

Journal of the American College of Radiology, 2009
Although the very first computed tomographic scanners used the iterative algebraic reconstruction technique, the filtered back-projection (FBP) method soon became the gold standard for computed tomographic reconstruction. Image quality has dramatically improved over the past 30 years thanks to advances in x-ray tubes, detector technologies, and overall

Preoperative Diagnosis of Gastric Tumors by Three-dimensional Multidetector Row CT and Double Contrast Barium Meal Study: Correlation with Surgical and Histologic Results

Journal of the Formosan Medical Association, 2007
Recent three-dimensional multidetector row computed tomography (3D MDCT) can provide detailed images of a gastric tumor, including its general contour, location and depth.

Contemporary Management of Aortic Stenosis: Timing of Intervention and Lifetime Valve Management

European Journal of Clinical Investigation, Volume 56, Issue 8, August 2026.
As transcatheter treatment expands to younger and lower‐risk patients, aortic stenosis management is evolving from a single procedure to lifelong valve care. This review highlights the key challenges across the patient journey, from timely diagnosis and optimal intervention to durable valve performance, long‐term surveillance, and repeat intervention ...

Preoperative Computed Tomography Colonography‐Angiography for Vascular Mapping to Guide and Standardize D3 Lymphadenectomy in Right‐Sided and Transverse Colon Cancer

Annals of Gastroenterological Surgery, Volume 10, Issue 4, Page 1120-1132, July 2026.
This study utilized high‐resolution CT colonography‐angiography to systematically classify vascular branching patterns in 591 patients. We defined four reproducible anatomical patterns each for right hemicolectomy and transverse colectomy, demonstrating that an independent‐origin middle colic artery consistently predicts shorter dissection distances ...

Comparison between multidetector computed tomography and hysterosalpingography in assessment of infertile couples

Middle East Fertility Society Journal, 2013
Objective: To compare the efficacy of multidetector CT (MDCT) with conventional X-ray hysterosalpingography (HSG) in the evaluation of infertile couples. Methods: Thirty-four patients with diagnosis of infertility, were evaluated with 4-row MDCT prior to

Prospective Trial of Radiofrequency Catheter Ablation of High Dominant Frequencies After Pulmonary Vein Isolation in Non‐Paroxysmal Atrial Fibrillation (PAD‐AF Trial): A Multicenter, Randomized Clinical Trial

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 7, Page 1410-1420, July 2026.
In persistent AF, adjunctive dominant frequency‐guided ablation after pulmonary vein isolation did not significantly improve outcomes. Limited overlap between high‐frequency sites and low‐voltage areas suggests functional–structural dissociation, while right atrial low‐voltage burden predicts recurrence.

MDCT Domain Enhancements For Audio Processing [PDF]

, 2010
Modified discrete cosine transform (MDCT) derived from DCT IV has emerged as the most suitable choice for transform domain audio coding applications due to its time domain alias cancellation property and de-correlation capability. In the present research

Comprehensive Study on Quantitative Evaluation of Oral Muscle Tissue in Children With Low Tongue Posture Using Cone Beam Computed Tomography: A Comprehensive Study on Nasal Ventilation Conditions Using Computational Fluid Dynamics

Journal of Oral Rehabilitation, Volume 53, Issue 7, Page 1337-1346, July 2026.
Measurement of nasal airway computed fluid dynamics, muscle‐fat tissue analysis in this study. Four typical examples illustrating the relationship between low tongue posture, nasal ventilation condition, and perioral muscle‐fat tissue are demonstrated in this study. A.
