Diagnostic and therapeutic interventional procedures are rapidly expanding and, when guided by imaging, are more efficient then when performed with a blinded technique. Compared to fluoroscopy and CT, ultrasound does not utilize ionizing radiation. ⋯ Technological improvements have increased the precision of ultrasound guidance and have contributed to reduce the risk of complication. Real time scanning allows simultaneous visualization of the target and of needle progression and has diminished the rate of complications, that are infrequent if the operator uses a strict sterile technique and respects the contraindications.

The advent of new MR techniques such as perfusion and diffusion weighted imaging has revolutionized diagnostic imaging in stroke. In some institutions, MRI is used as the sole screening imaging technique for acute stroke patients. In this document, the authors will review the MR pattern of acute ischemic arterial stroke, highlight the usefulness of MRI for the identification of acute hematomas and stroke like episodes, present the potential use of MRI in the management of acute stroke patients, especially when thrombolysis is contemplated, and discuss the role of MRI for imaging transient ischemic attack.

Case Reports
[Gartner's cyst communicating with the bladder and vagina with associated complete vaginal diaphragm].
Gartner's duct cyst is a relatively common benign cystic lesion and represents embryologic remnants of Wolffian ducts. These cysts are usually small and asymptomatic and have been reported to occur in as many as 1% of all women. ⋯ The diagnosis of Gartner's duct cyst was suggested by pelvic ultrasonography and MR imaging. Vaginal diaphragm and communication between the Gartner's cyst, the bladder and vagina were established during cystoscopy and vaginoscopy.

Case Reports
[Percutaneous treatment of a gas containing epidural pseudocyst: an uncommon cause of sciatica].
Gas containing epidural pseudocyst is a rare cause of lumbar radicular compression. We present the case of a 42 year old woman presenting with right L5 radicular pain. ⋯ Resolution of radicular pain occurred following CT guided aspiration and steroid injection. The patient remained asymptomatic at one year follow-up.
