NCT ID: NCT05111496 Recruiting - Clinical trials for Chronic Total Occlusion

Evaluation of the Radiological Dose Delivered to Risky Interventional Cardiology Patients (Optidose)

Optidose
Start date: September 24, 2020
Phase:
Study type: Observational

The purpose of this study is therefore to study the actual doses of X-rays delivered to the patient's skin during recanalization of a coronary artery in a context of Chronic Total Occlusion

NCT ID: NCT04762615 Completed - Immunosuppression Clinical Trials

Impact of Underlying Renal Disease and Immunosuppressive Regimen on Ovarian Reserve in Renal Patients

Start date: June 1, 2018
Phase:
Study type: Observational [Patient Registry]

Aging, renal pathology (eg SLE, ADPKD), X-ray exposition and pharmacological treatments, especially previous strong immunosuppression, may negatively influence the ovarian reserve in childbearing age women. Anti-Müllerian hormone (AMH) is regarded as biomarker for ovarian reserve. Every female with renal disease regularly menstruating that met exclusion criteria could have participated. The aim was to assess ovarian reserve in female patients with normal menstrual cycle and kidney disease, including kidney transplant recipients.

NCT ID: NCT04005040 Completed - Clinical trials for Patient Satisfaction

Evaluation of Mobile X-ray Within the Triple Aim Method

Start date: May 1, 2018
Phase: N/A
Study type: Interventional

Background: In foreign countries, mobile x-ray already is being used where transfer to the radiology department at the hospital may be an obstacle. Using mobile x-ray, the x-ray examination is performed in the patients own home with transportable equipment that reminds of the transportable x-ray equipment that is being used in the intensive care units. At The Department of Radiology (DOR), Aarhus University Hospital there is an ongoing project mobile x-ray for patients living in nursing homes in Aarhus. The project will be evaluated inspired by the Triple Aim Approach in three sub studies. Overall aim: The overall aim is to conclude if mobile x-ray improves healthcare for fragile patients. Hypotheses: - Patients examined with mobile x-ray have fewer number of hospital admissions compared with patients examined with x-ray at DOR. - Patients examined with mobile x-ray are more satisfied with their examination compared with patients examined with x-ray at DOR. Sub study 1 - Population health Aim: The primary aim is to study if mobile x-ray improves the health of the defined population measured in hospital admission. Also to study challenges conducting a RCT. The outcome measures: The primary outcome is hospital admissions. Sub study 2 - Experience of care Aim: The aim is to study the satisfaction with mobile x-ray compared the satisfaction to x-ray at DOR. Methods: Observations, interview and questionnaires.

NCT ID: NCT03259126 Completed - Coronary Disease Clinical Trials

EXTended pRotective Curtain Under Table to Reduce Operator RAdiation Dose in Percutaneous Coronary Procedures

EXTRA-RAD
Start date: August 7, 2017
Phase: N/A
Study type: Interventional

Radiation dose to interventional cardiologists performing transradial percutaneous coronary procedures is higher compared to those performing transfemoral exams. The radiation dose seems particularly high at pelvic level. We prepared an home-made protective extension of the leaded curtain under table that should reduce the operator exposure during interventional coronary procedures. The aim of the study is to evaluate the procedural efficacy of the protective extension on the operator radiation dose at pelvic level

NCT ID: NCT03033615 Not yet recruiting - Cancer, Lung Clinical Trials

PixelShine vs. Iterative Reconstruction (IR) Processing of CT Images

Start date: August 2017
Phase: N/A
Study type: Interventional

This study will compare the quality of CT images acquired with very low-dose radiation and processed with commercially available software vs. PixelShine processed images. It would potentially allow imaging facilities to acquire CT scans using lower doses of radiation without sacrificing clarity of CT images. Acquiring high quality CT images with low-dose radiation has the potential to enhance patient safety and has significant implications in imaging practices.

NCT ID: NCT02813122 Completed - X-rays; Effects Clinical Trials

The Use of X-ray in Bariatric Surgeries

Start date: June 2016
Phase: N/A
Study type: Observational

examination of the importance of the use of X-ray in bariatric surgery outcome.

NCT ID: NCT02358447 Completed - Osteoarthritis Clinical Trials

SPECT-CT for Assessment of Total Knee Arthroplasty in Navigated and Non-navigated Total Knee Arthroplasty

Start date: April 2010
Phase:
Study type: Observational

By the comparison of two operation methods navigated and non-navigated TKR with SPECT/CT we want to show wich method has the better outcome.
