Quality assessment of cardiovascular magnetic resonance in the setting of the European CMR registry: description and validation of standardized criteria.

BACKGROUND: Cardiovascular magnetic resonance (CMR) has become an important diagnostic imaging modality in cardiovascular medicine. However, insufficient image quality may compromise its diagnostic accuracy. We aimed to describe and validate standardized criteria to evaluate a) cine steady-state free precession (SSFP), b) late gadolinium enhancement (LGE), and c) stress first-pass perfusion images. These criteria will serve for quality assessment in the setting of the Euro-CMR registry. METHODS: Thirty-five qualitative criteria were defined (scores 0-3) with lower scores indicating better image quality. In addition, quantitative parameters were measured yielding 2 additional quality criteria, i.e. signal-to-noise ratio (SNR) of non-infarcted myocardium (as a measure of correct signal nulling of healthy myocardium) for LGE and % signal increase during contrast medium first-pass for perfusion images. These qualitative and quantitative criteria were assessed in a total of 90 patients (60 patients scanned at our own institution at 1.5T (n=30) and 3T (n=30) and in 30 patients randomly chosen from the Euro-CMR registry examined at 1.5T). Analyses were performed by 2 SCMR level-3 experts, 1 trained study nurse, and 1 trained medical student. RESULTS: The global quality score was 6.7±4.6 (n=90, mean of 4 observers, maximum possible score 64), range 6.4-6.9 (p=0.76 between observers). It ranged from 4.0-4.3 for 1.5T (p=0.96 between observers), from 5.9-6.9 for 3T (p=0.33 between observers), and from 8.6-10.3 for the Euro-CMR cases (p=0.40 between observers). The inter- (n=4) and intra-observer (n=2) agreement for the global quality score, i.e. the percentage of assignments to the same quality tertile ranged from 80% to 88% and from 90% to 98%, respectively. The agreement for the quantitative assessment for LGE images (scores 0-2 for SNR <2, 2-5, >5, respectively) ranged from 78-84% for the entire population, and 70-93% at 1.5T, 64-88% at 3T, and 72-90% for the Euro-CMR cases. The agreement for perfusion images (scores 0-2 for %SI increase >200%, 100%-200%,<100%, respectively) ranged from 81-91% for the entire population, and 76-100% at 1.5T, 67-96% at 3T, and 62-90% for the Euro-CMR registry cases. The intra-class correlation coefficient for the global quality score was 0.83. CONCLUSIONS: The described criteria for the assessment of CMR image quality are robust with a good inter- and intra-observer agreement. Further research is needed to define the impact of image quality on the diagnostic and prognostic yield of CMR studies.

Review of Thompsoniella Guimarães with description of a new species from Colombia (Diptera, Calliphoridae, Mesembrinellinae)

Review of Thompsoniella Guimarães with description of a new species from Colombia (Diptera, Calliphoridae, Mesembrinellinae). The Mesembrinellinae (Diptera, Calliphoridae) are exclusively Neotropical with nine genera comprising 36 recognized species, including the genus Thompsoniella Guimarães with a single species, T. anomala Guimarães. We describe a new species, Thompsoniella andina sp. nov., from the Departments of Antioquia and Caldas, Colombia (Cordillera Central of the Andes, between 2600 - 2700 m) and redescribe T. anomala. A key to the nine genera of Mesembrinellinae and a key to the males of the two species of Thompsoniella are provided. Color photographs to illustrate the two species of Thompsoniella and drawings of the male genitalia of both species are also provided. Here we record Thompsoniella for the first time in Colombia.

Description of the male of Evandromyia gaucha Andrade Filho, Souza, Falcão (Psychodidae, Phlebotominae)

Here, we present the description of male of the sand fly species Evandromyia gaucha. Six male specimens of E. gaucha, together with conspecific females, were collected in native forest areas of the municipalities of Porto Alegre, Caçapava do Sul (type locality of E. gaucha) and Santa Cruz do Sul, in Rio Grande do Sul state, Brazil. The specimens are distinguished from other species of the rupicola series of the genus Evandromyia by the presence of dilatation in the apical quarter of the genital filaments followed by tapering of the final portion.

Description of a new species of Psathyromyia Barreto (Diptera, Psychodidae, Phlebotominae) from Amazonas state, Brazil

ABSTRACTA new species of phlebotomine sand fly is described and illustrated based on the male and female morphological characters of specimens collected from Tefé and Coari municipalities, Amazonas state. The phlebotomine sand flies were collected with CDC light traps used as aspirators at the base of tree trunks. Both male and female specimens collected in Tefé municipality were first identified as Psathyromyia souzacastroi. After the analysis of the holotype of Pa. souzacastroi deposited in Smithsonian Institute/Walter Reed Biosystematics Unit, it was observed that the morphotypes collected in Tefé municipality belong to a distinct species, which characterization is here presented.
