Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective is to evaluate whether one-phase nephrographic CT (experimental) is sufficient to detect urothelial cell carcinoma in patients with hematuria compared to the traditional four-phase CT (control).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Responsible centers Oslo University Hospital, Aker. Division of Radiology and Nuclear medicine.

Study type: Prospective clinical trial

Study design: One sample paired proportion, non-inferiority study with a 7.5% non-inferiority limit.

Investigational product: One phase nephrographic CT (experimental arm) vs. Four-phase CT (control arm)

Objective:The primary objective is to evaluate whether one-phase nephrographic CT (experimental) is sufficient to detect urothelial cell carcinoma in patients with asymptomatic macroscopic hematuria compared to the traditional four-phase CT (control).

Primary endpoints: The difference in accuracy between the experimental- and control arm.

there will also be a secondary reading in order to asses interobserver variability for both the experimental and the control arm

Sample size: 250 patients

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

One sample, paired, non-inferiority study with a 7.5% non-inferiority limit. Each patient undergo the experimental CT and the control CT
Primary Study Purpose

DIAGNOSTIC

Blinding Strategy

NONE

one investigator evaluates the experimental arm a second investigator evaluates the control arm without knowledge of the other

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

nephrographic phase CT

the nephrographic phase will be evaluated alone by a radiologist blinded to the remaining series

Group Type EXPERIMENTAL

CT

Intervention Type DIAGNOSTIC_TEST

the CT consist of four phases; non-enhanced, corticomedullary, nephrographic and excretory phase.

gold standard

all series (unenhanced, corticomedullary, nephrographic and excretory phase) will be evaluated by a radiologist not involved in the experimental arm

Group Type ACTIVE_COMPARATOR

CT

Intervention Type DIAGNOSTIC_TEST

the CT consist of four phases; non-enhanced, corticomedullary, nephrographic and excretory phase.
