Incremental diagnostic utility of delayed enhancement CMR tissue characterization for detection of catheter associated right atrial thrombus
نویسندگان
چکیده
Methods The population comprised consecutive patients with central venous catheters undergoing CMR at Memorial Sloan Kettering Cancer Center (NY, NY). Delayed enhancement CMR (inversion recovery GRE) was used to identify RT; defined as a right atrial (RA) mass with avascular tissue characteristics (non-enhancing) on “long TI” (600msec) DE-CMR. Cine-CMR (SSFP) was used to quantify cardiac structure and function, including RA and RV function and chamber size. Clinical indices were categorized based on medical record review. Echo (if performed within 14 days of CMR) was retrieved from image archives and independently read for RT. Clinical records were queried for documented pulmonary embolus (PE) within 60 days of CMR.

Contrast-enhanced anatomic imaging as compared to contrast-enhanced tissue characterization for detection of left ventricular thrombus.
OBJECTIVES This study sought to compare contrast-enhanced anatomic imaging and contrast-enhanced tissue characterization (delayed-enhancement cardiac magnetic resonance [DE-CMR]) for left ventricular (LV) thrombus detection. BACKGROUND Contrast echocardiography (echo) detects LV thrombus based on anatomic appearance, whereas DE-CMR imaging detects thrombus based on tissue characteristics. Alt...

BACKGROUND Late gadolinium enhancement (LGE-) cardiovascular magnetic resonance (CMR) is well-validated for cardiac mass (CMASS) tissue characterization to differentiate neoplasm (CNEO) from thrombus (CTHR): Prognostic implications of CMASS subtypes among systemic cancer patients are unknown. METHODS CMASS + patients and controls (CMASS -) matched for cancer diagnosis and stage underwent a st...

OBJECTIVES This study sought to assess the prevalence and markers of left ventricular (LV) thrombus among patients with systolic dysfunction. BACKGROUND Prior studies have yielded discordant findings regarding prevalence and markers of LV thrombus. Delayed-enhancement cardiovascular magnetic resonance (DE-CMR) identifies thrombus on the basis of tissue characteristics rather than just anatomi...

BACKGROUND Cardiac magnetic resonance (CMR) imaging is well validated for tissue characterization of cardiac masses but has not been applied to study pattern and prognostic implications of cardiac metastases (CMETs) among patients with systemic cancer. METHODS AND RESULTS The population consisted of 60 patients with stage IV cancer (32 patients with CMETs, 28 diagnosis-matched controls) under...
متن کاملThrombus can enhance on delayed enhancement imaging
Background To examine the diagnostic accuracy of cardiac magnetic resonance imaging (CMR) in differentiating thrombus from myxoma Thrombus is thought not to enhance on CMR, myxomas are thought to show mild heterogenous enhancement on delayed imaging. It is sometimes difficult to differentiate them, and this may lead to misdiagnosis, which would significantly impact treatment. Thrombi can have v...
