The purpose of this study was to analyze the MDCT and MRI findings in patients with unroofed coronary sinus syndrome. ⋯ CT and MRI facilitate definite diagnosis of unroofed coronary sinus syndrome.

Comparative StudyPostmortem imaging-guided biopsy as an adjuvant to minimally invasive autopsy with CT and postmortem angiography: a feasibility study.
Although postmortem CT suffices for diagnosing most forms of traumatic death, the examination of natural death is, to date, very difficult and error prone. The introduction of postmortem angiography has led to improved radiologic diagnoses of natural deaths. Nevertheless, histologic changes to tissues, an important aspect in traditional examination procedures, remain obscure even with CT and CT angiography. For this reason, we examined the accuracy of a minimally invasive procedure (i.e., CT angiography combined with biopsy) in diagnosing major findings and the cause of death in natural deaths. ⋯ In light of increasing objections of the next of kin toward an autopsy and the necessity for medical examiners to assess the manner and cause of death, we think that the minimally invasive procedure described here may present a viable compromise in selected cases.

Knowledge and attitudes of emergency department patients regarding radiation risk of CT: Effects of age, sex, race, education, insurance, body mass index, pain, and seriousness of illness.
The purpose of this study was to assess knowledge and attitudes about radiation from CT among emergency department patients with symptoms prompting CT who were stratified on the basis of demographic variables, pain, and perceived illness. ⋯ Patients did not estimate the risk of development of cancer from their imaging examinations as high and were more concerned about having their condition diagnosed with CT than about the risk of future cancer. Knowledge and attitudes differed by age, race, education, insurance status, and pain level but not by sex, body mass index, or perceived seriousness of condition.

Assessment of right ventricular function in acute pulmonary embolism using ECG-synchronized MDCT.
The purpose of this article is to determine the independent predictors of right ventricular (RV) dysfunction in patients with acute pulmonary embolism (PE) and to assess the relationship between RV ejection fraction (EF) and PE load. ⋯ RV dysfunction (defined as RV EF < 35%) in patients with acute PE is highly sensitive to define a PE load greater than 50%. Furthermore, RV dysfunction is independently predicted by an obstruction index greater than 50% or an LV EF less than 45%. Assessment of RV function by ECG-synchronized CT may become useful for guiding therapy.
