Objectives
This study sought to investigate the potential of the noninvasive albumin-binding probe gadofosveset-enhanced cardiac magnetic resonance (GE-CMR) for detection of coronary plaques that can cause acute coronary syndromes (ACS).Background
ACS are frequently caused by rupture or erosion of coronary plaques that initially do not cause hemodynamically significant stenosis and are therefore not detected by invasive x-ray coronary angiography (XCA).Methods
A total of 25 patients with ACS or symptoms of stable coronary artery disease underwent GE-CMR, clinically indicated XCA, and optical coherence tomography (OCT) within 24 h. GE-CMR was performed approximately 24 h following a 1-time application of gadofosveset-trisodium. Contrast-to-noise ratio (CNR) was quantified within coronary segments in comparison with blood signal.Results
A total of 207 coronary segments were analyzed on GE-CMR. Segments containing a culprit lesion in ACS patients (n = 11) showed significant higher signal enhancement (CNR) following gadofosveset-trisodium application than segments without culprit lesions (n = 196; 6.1 [3.9 to 16.5] vs. 2.1 [0.5 to 3.5]; p < 0.001). GE-CMR was able to correctly identify culprit coronary lesions in 9 of 11 segments (sensitivity 82%) and correctly excluded culprit coronary lesions in 162 of 195 segments (specificity 83%). Additionally, segmented areas of thin-cap fibroatheroma (n = 22) as seen on OCT demonstrated significantly higher CNR than segments without coronary plaque or segments containing early atherosclerotic lesions (n = 185; 9.2 [3.3 to 13.7] vs. 2.1 [0.5 to 3.4]; p = 0.001).Conclusions
In this study, we demonstrated for the first time the noninvasive detection of culprit coronary lesions and thin-cap fibroatheroma of the coronary arteries in vivo by using GE-CMR. This method may represent a novel approach for noninvasive cardiovascular risk prediction. 相似文献293.

Adrenal injuries following blunt abdominal trauma are uncommon. Adrenal hemorrhage in children associated with multiple organ injury, which has received little attention in the past, is an increasingly recognized phenomenon in modern trauma centers with the widespread use of abdominal computed tomography. Adrenal trauma occurs in the setting of multisystem organ injury. Isolated adrenal injury is exceedingly rare. We report two children with blunt adrenal trauma (one isolated and one with associated injuries), who were admitted during the last two years to our Pediatric Surgery Department after abdominal trauma. We determined the prevalence, management and general prognosis of blunt adrenal injury in the pediatric population. Traumatic adrenal hemorrhage appears to be an incidental and unsuspected finding that resolves on follow-up imaging. 相似文献

Granular cell tumour (or Abrikossoff's tumour) was first described by Abrikossoff in 1926. This is a rare benign neoplasm of unclear histogenesis that is generally believed to be of nerve sheath origin. Usually, it presents as a solitary lesion, located mainly in the subcutaneous tissue of the head, or the neck, or in the oral cavity, such as a tongue lesion, although it may develop anywhere in the body. Approximately 1-2% of granular cell tumours are malignant. Granular cell tumours are extremely rare in patients with inflammatory bowel disease. To the best of our knowledge, granular cell tumours have never been reported in association either with Crohn's disease or scheduled infliximab treatment. Herein, we report a case of a granular cell tumour that presented as a subcutaneous skin nodule of the right lumbar area without any associated local or systemic symptoms in a 41-year-old woman with Crohn's disease who was receiving scheduled treatment with infliximab (5 mg/kg every 8 weeks) for 7 years. 相似文献
