Review Case Reports
Multiple pulmonary artery pseudoaneurysms: intrasaccular embolization.
We report the case of a 32-year-old female presenting with two pulmonary artery false aneurysms of mycotic origin. Considering the natural history and potential complications, we treated the patient by intrasaccular embolization with steel coils. No complication occurred.

We report a case of posttraumatic intestinal stenosis (PIS), an uncommon sequela of blunt abdominal trauma, in which injury to the mesentery and bowel wall results in later focal ischemic stricture of that segment. We include CT images at the time of trauma, and barium meal and abdominal sonography obtained during the subsequent admission. ⋯ This is the first report which includes both imaging at the time of trauma and sonographic appearance of the narrowed bowel loop. Posttraumatic intestinal stenosis should be considered in the differential diagnosis of a narrowed bowel loop in a patient with a history of blunt abdominal trauma.

Randomized Controlled Trial Comparative Study Clinical Trial
Use of a 22-gauge Whitacre needle to reduce the incidence of side effects after lumbar myelography: a prospective randomised study comparing Whitacre and Quincke spinal needles.
In a prospective study lumbar iohexol myelography was performed in 107 consecutive patients, randomised for lumbar puncture with a Quincke or Whitacre spinal needle. All patients answered a questionnaire about possible side effects. Data from 100 patients (58 men, 42 women) were evaluated. ⋯ In the Whitacre group (n = 47), 33 (70%) had no side effects. PDPH was reported by 9 patients (19%), of whom 2 had mild, 6 moderate and only 1 (2%) severe cephalalgia, 4 (9%) reported increased low back pain/sciatica, 5 nausea and 4 dizziness. The conclusion drawn from this study is that lumbar myelography performed with the Whitacre spinal needle reduces postspinal side effects.

Comparative Study
Breath-hold MR imaging of focal liver lesions: comparison of fast and ultrasound techniques.
The performance of breath-hold MR imaging using two T2-weighted hybrid sequences (TSE, TGSE), two T2-weighted single-shot sequences (HASTE, EPI-SE), and one T1-weighted gradient-echo sequence (FLASH) was compared with a standard conventional T2-weighted SE sequence in 20 patients with focal liver lesions. Liver signal-to-noise ratio was highest for the FLASH sequence (54.3 +/- 8.3) and the HASTE (41.1 +/- 12.5) sequence, whereas the highest spleen-liver contrast-to-noise ratio was obtained by the TSE sequence (38.9 +/- 20.7). ⋯ With both TSE and HASTE significantly (p < 0.01) more lesions were detected as compared with SE and EPI-SE sequences. Our results indicate that breath-hold TSE and HASTE sequences will eventually replace conventional T2-weighted SE techniques, due to their insensitivity to motion artifacts, superior lesion detectability and inherently short acquisition times.
