Vascular Diseases of the Spleen: A Review.

Vascular diseases of the spleen are relatively uncommon in the clinical practice. However, the reported incidence has been progressively increasing, probably due to advances in the imaging modalities used to detect them. This disease condition often presents with non-specific clinical manifestations, but can be associated with significant morbidity and mortality.

Feasibility of Echocardiographic Techniques to Detect Subclinical Cancer Therapeutics-Related Cardiac Dysfunction among High-Dose Patients When Compared with Cardiac Magnetic Resonance Imaging.

Background: Cardiac magnetic resonance imaging (CMR) is the gold standard for the quantification of global and regional myocardial function and can detect subclinical myocardial dysfunction in anthracycline-induced cardiomyopathy. The aim of this study was to ascertain reliable echocardiographic parameters that can be used for the early identification of cancer therapeutics-related cardiac dysfunction, compared with CMR.

Methods: Fifty-seven pediatric cancer survivors, 10 to 42 years of age, with cumulative anthracycline doses ≥ 200 mg/m(2), were studied with transthoracic echocardiography and CMR 2.

Occult cardiotoxicity in childhood cancer survivors exposed to anthracycline therapy.

Background: More than 50% of >270 000 childhood cancer survivors in the United States have been treated with anthracyclines and are therefore at risk of developing cardiotoxicity. Cardiac magnetic resonance (CMR) has demonstrated utility to detect diffuse interstitial fibrosis and changes in regional myocardial function. We hypothesized that CMR would identify occult cardiotoxicity characterized by structural and functional myocardial abnormalities in a cohort of asymptomatic pediatric cancer survivors with normal global systolic function.

Dose of reduced z-axis length of computed tomography angiography (CTA) of the chest for pulmonary embolism using 64-detector rows and adaptive iterative reconstruction techniques.

The objective of this study is to compare the dose of CT angiography (CTA) for the diagnosis of pulmonary embolism (PE) performed using a reduced z-axis to conventional CTA for PE, both using adaptive iterative reconstruction technique on a 64-detector row device. The institutional review board approved a waiver of informed consent. A study was performed to consecutive patients having CTA for PE in the emergency department (ED).

Transient osteoporosis of pregnancy in a 34-year-old female.

A 34-year-old Caucasian female presented during the third trimester of her pregnancy with bilateral hip pain that became progressively severe. Imaging of her pelvis and bilateral hips with MRI obtained during her third trimester of pregnancy demonstrated bilateral bone-marrow edema of the femoral heads and the sacrum at S1. Repeat MRI performed at 6 months postpartum revealed resolution of edema.

A psychoanalytic exploration of collective trauma among Indigenous Australians and a suggestion for intervention.

Objective: Psychoanalysis is used to explore the effects of the annihilation of culture and how this leads to a loss of identification with a collective subjectivity and triggers catastrophic symptoms including loss of collective hope, the rise of addictive and self-destructive behaviours, and the intergenerational transmission of trauma among Indigenous Australian communities.

Conclusions: I propose restorative educational interventions for young Indigenous children that seek to engage them with ancestral memory, cultural narratives, and a sense of purpose so that healing from historically transmitted trauma may be initiated and a grounded sense of subjectivity restored.

Reduced Z-axis coverage multidetector CT angiography for suspected acute pulmonary embolism could decrease dose and maintain diagnostic accuracy.

Multidetector computed tomographic angiography (MDCTA) is the method of choice for evaluation of suspected acute pulmonary embolism (PE) in most patients because it is accurate and widely available. The use of computed tomography, including MDCTA for PE, has risen dramatically over the last several years with an attendant rise in radiation exposure. Many methods currently employed to reduce radiation dose may affect image quality and potentially affect diagnostic accuracy.

Added cancer yield of MRI in screening the contralateral breast of women recently diagnosed with breast cancer: results from the International Breast Magnetic Resonance Consortium (IBMC) trial.

Objective: To estimate the added cancer yield of magnetic resonance imaging (MRI) over mammography in the contralateral breast of patients with a recent diagnosis of breast cancer.

Methods: We conducted a prospective, international study of mammography and MRI in women with a recent diagnosis of unilateral breast cancer. Each subject received a mammogram, clinical breast exam (CBE), and MRI of the unaffected breast within a 90 day time period.

Screening women at high risk for breast cancer with mammography and magnetic resonance imaging.

Background: The authors compared the performance of screening mammography versus magnetic resonance imaging (MRI) in women at genetically high risk for breast cancer.

Methods: The authors conducted an international prospective study of screening mammography and MRI in asymptomatic, genetically high-risk women age >/= 25 years. Women with a history of breast cancer were eligible for a contralateral screening if they had been diagnosed within 5 years or a bilateral screening if they had been diagnosed > 5 years previously.

Sonographically guided percutaneous radio frequency ablation of a renal cell carcinoma in a transplanted kidney.

Radio frequency ablation is an effective treatment for focal renal cell carcinoma (RCC). We report a patient with RCC in a transplanted kidney that was successfully treated with percutaneous sonographically guided radio frequency ablation.
