We compared two-dimensional (2D) and three-dimensional (3D) inversion recovery prepared (IR) fast gradient echo (FGRE) and steady state free precession (SSFP) sequences used in myocardial delayed enhancement imaging. Twenty patients with a prior history of acute coronary syndrome were included in this study. Breath hold, ECG gated, segmented 2D and 3D IR_FGRE and SSFP sequences were acquired after intravenous administration of 0.15 mmol/kg gadodiamide-DTPA. Overall image quality, transmural extent of myocardial infarction, infarct volume, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and signal intensity ratio (SIR) were calculated and compared for each technique. 3D IR trueFISP showed significantly higher mean values of SNR and CNR compared with 3D IR turboFLASH, 2D IR turboFLASH and 2D IR trueFISP (p < 0.04 and p < 0.001). 3D IR_FGRE showed the second highest SNR and CNR. 3D IR_SSFP and 3D IR_FGRE allowed the imaging of the whole heart within a single breath-hold which reduced the imaging time significantly compared to 2D IR_FGRE and 2D IR_SSFP. 3D IR_SSFP and 3D IR_FGRE offer higher SNR, CNR and rapid acquisiton compared to 2D IR_SSFP and 2D IR_FGRE with adequate image quality.

The purpose of this retrospective study was to evaluate the diagnostic accuracy of CT-fluoroscopic transthoracic biopsy of pulmonary lesions related to their localization and size. The complication rate was also evaluated. Between January 2003 and June 2004, we performed seventy-two CT-fluoroscopic transthoracic biopsies in sixty-nine patients. ⋯ Pneumothoraces were observed in only 7 patients (10%) and there was only 1 small postpuncture hemothorax (1.7%). CT-fluoroscopic biopsy of pulmonary lesions has a good diagnostic accuracy with a very low complication rate. The accuracy is higher for larger lesions, but there is no significant difference for subpleural and peripheral lesions.

We report a rare case of esophageal intramural pseudodiverticulosis with perforation of the esophagus. A 32-year-old male presented with acute thoracal pain after a period of vomiting. ⋯ During the following thoracic surgery procedure no macroscopic site of rupture could be identified. Pseudodiverticulosis was detected during a barium swallow exam of the esophagus 4 weeks later.
