Exploiting endovascular aortic repair as a minimally invasive method - Nine years of experience in a non-university hospital.

Background: At the introduction of endovascular aortic repair (EVAR) in 2013 in our non-university hospital, we established a quality registry to monitor our EVAR activity.

Purpose: To observe if we over time were able to exploit EVAR as a minimally invasive method in an elective as well as emergency setting, and to monitor our treatment quality in terms of complications, secondary interventions and mortality.

Material And Methods: From November 2013 to March 2022, we treated 207 patients with EVAR, including six patients with rupture.

Corynebacterium pseudotuberculosis Pneumonia in a Veterinary Student Infected During Laboratory Work.

We present a case of Corynebacterium pseudotuberculosis pneumonia in a veterinary student, with molecular genetic evidence of acquisition during laboratory work, an observation relevant for laboratory personnel working with C pseudotuberculosis isolates. The patient was clinically cured with 14 months trimethoprim/sulfamethoxazole and rifampicin combination treatment.

Radiation knowledge and perception of referral practice among radiologists and radiographers compared with referring clinicians.

Objectives: To explore if the perception of radiologists and radiographers on referral practice differs from that of referring clinicians, and to see if knowledge of radiation issues and referral guidelines differ between these groups.

Methods: A questionnaire was handed out to 46 radiologists and 36 radiographers in Norway. Findings were compared to corresponding results from a similar already published study on clinicians.

Application of adaptive non-linear 2D and 3D postprocessing filters for reduced dose abdominal CT.

Background: Abdominal computed tomography (CT) is a frequently performed imaging procedure, resulting in considerable radiation doses to the patient population. Postprocessing filters are one of several dose reduction measures that might help to reduce radiation doses without loss of image quality.

Purpose: To assess and compare the effect of two- and three-dimensional (2D, 3D) non-linear adaptive filters on reduced dose abdominal CT images.

Clinicians' justification of imaging: do radiation issues play a role?

OBJECTIVE: To explore clinicians' knowledge and consideration of radiation, in relation to their referral practice and use of referral guidelines for imaging. METHODS: A questionnaire was handed out to 213 clinicians in Norway; all responded: 77 general practitioners, 71 hospital physicians and 65 non-physicians (55 manual physiotherapists, 10 chiropractors). Questions concerned weighting of radiation dose, guideline use, referrals unlikely to affect treatment, doses from imaging procedures, ranking of imaging as radiation source, and deterministic and stochastic effects.

Shift in imaging modalities of the urinary tract over a 25-year period and its impact on ionizing radiation doses given to patients.

Objectives: To explore the shift in imaging modalities used when examining the urinary tract over the period 1979-2003 and to see how this shift, together with a radiation protection policy, have influenced the doses of ionizing radiation used.

Material And Methods: Activity reports from a department of radiology were reviewed. Relevant radiation dose estimates were obtained from the Norwegian Radiation Protection Authority.

Shift in imaging modalities of gastrointestinal tract through 25 years and its impact on patient ionizing radiation doses.

We wanted to explore the shift in modalities when diagnosing the gastrointestinal tract through the last three decades and see how this has influenced on the radiation doses given to this patient population. Activity reports from a central hospital in the years of 1979-2003 have been reviewed. The x-ray based modalities have decreased, while there has been a marked increase in colonoscopies, gastroscopies, ultrasound, and magnetic resonance cholangiopancreatography.

Shift in imaging modalities of the spine through 25 years and its impact on patient ionizing radiation doses.

Study Design: Retrospective.

Objective: To explore the shift in modalities when diagnosing the spine in the years 1979-2003. To see how this shift, together with a radiation protective policy, have influenced on the ionizing radiation doses.
