MR image analysis of ex-vivo mouse model of heart ischemia.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionMyocardial infarction is one of the major causes of death and disability. Various diagnostic modalities used to investigate cardiac ischaemia. Advances in Magnetic Resonance Imaging technology has opened up new horizons for investigating the cardiac function and quantifying any pathology that may be present.
aimsThe present study was designed to quantify the cardiac area at risk and infarction reperfusion areas using the mismatch of iron oxide contrast and gadolinium (Gd) contrast imaging (MRIs) and to test if a combination of T1, T2, and iron oxide T2* contrasts will distinguish the infarction and AAR zones.
methodsA well-established mouse model was used to induced cardiac ischaemia and reperfusion. Six mice models' hearts were harvested and processed according to various protocols. MI was induced through ligation technique for five mice, and one was kept as normal control. MR imaging and Reperfusion were performed using a Three-dimensional gradient-echo fast low angle shot
resultsThe edematous myocardium had significant high signal intensity in 3DMSME with variable echo time (14, 28, 42 ms). The combination of 3DFLASH and 3DMSME at an echo time of 42 ms was statistically significant, detecting the AAR more accurately. Both T1 and T2 sequences had the potential to determine the AAR zone. The infarct area has significantly high signal intensity compared to normal areas (p = 0.04 for the T1 map and p = 0.01 for the T2 map).
conclusionsThe study demonstrated that Cardiac MRI was a valuable technology to investigate infarct areas and zones that are at risk.
