Dual-energy computed tomography as a lower radiation dose alternative to perfusion computed tomography in tumor viability assessment.

To present the utility of dual-energy computed tomography (DECT) in the assessment of angiogenesis of focal lesions as an example of a solitary pulmonary nodule (SPN). This prospective study comprised 28 patients with SPN who underwent DECT and perfusion computed tomography (CTP), according to a proprietary protocol. Two radiologists independently analyzed four perfusion parameters, namely blood flow (BF), blood volume (BV), the time to maximum of the tissue residue function (Tmax), permeability surface area product (PS) from CTP, in addition to the iodine concentration (IC) and normalized iodine concentration (NIC) of the SPN from DECT.

The aim of this study was to analyze (using monochromatic DECT images) how the X-ray absorption of solitary pulmonary nodules (SPNs) depends on the iodine contrast agent and when X-ray absorption is no longer dependent on the accumulated contrast agent. Sixty-six patients with diagnosed solid lung tumors underwent DECT scans in the late arterial phase (AP) and venous phase (VP) between January 2017 and June 2018.

Purpose: To evaluate the brain perfusion with MRI perfusion weighted imaging (PWI) before and after ICA stenting in asymptomatic and symptomatic patients.

Materials And Methods: PWI was performed 3-21 days before and 3 days after ICA stenting in 31 asymptomatic patients with ICA >70% stenosis - Group I, and in 14 symptomatic patients with ICA >50% stenosis - Group II. PWI was evaluated qualitatively and quantitatively in 5 cerebral territories with: mean transit time (MTT), cerebral blood volume (CBV) and cerebral blood flow (CBF).

[Damage of the lungs after exposure to obscurant smoke - a case report].

Firing smoke candle, on reaction of pyrotechnic mixture of zinc oxide and hexachloroethane, releases of white smoke, which can damage the pulmonary parenchyma. Presented case illustrates the effects of such an inhalation injury that has led to acute respiratory distress syndrome (ARDS). The use of mechanical ventilation and administration of antibiotics and corticosteroids give the possibility to obtain clinical improvement.

Right ventricular outflow tract obstruction as a confounding factor in the assessment of the impact of pulmonary regurgitation on the right ventricular size and function in patients after repair of tetralogy of Fallot.

Purpose: To compare right ventricular (RV) size and function between patients with combined pulmonary regurgitation (PR) plus RV outflow tract (RVOT) obstruction (RVOTO) and patients with isolated PR.

Materials And Methods: Consecutive individuals with significant PR (PR fraction ≥ 20%) after tetralogy of Fallot (TOF) repair who underwent cardiovascular magnetic resonance (CMR) were included. Patients with additional hemodynamic abnormalities (residual ventricular septal defect, extracardiac shunt, and/or more than mild regurgitation at a valve other than the pulmonary valve) were excluded.

Comparison between maximal left ventricular wall thickness and left ventricular mass in patients with hypertrophic cardiomyopathy.

Background: Cardiovascular magnetic resonance enables accurate and reproducible assessment of left ventricular (LV) dimensions and function, free of geometric assumptions and limitations related to an inadequate acoustic window.
