DWI Reversal Is Associated with Small Infarct Volume in Patients with TIA and Minor Stroke

Fellows’ Journal Club
April 2014

(1 of 3)

The implications of the reversal of DWI abnormalities in patients with TIA and minor strokes were assessed. Patients were imaged within 24 hours of symptoms and followed for 3 months and baseline and final infarct volumes were calculated using DWI and FLAIR, respectively. Over 55% of patients had DWI lesions and 37% had perfusion deficits. DWI reversal occurred in 6% of patients with lesion volume being considerably smaller than in those that did not reverse. Perfusion abnormalities were less common in reversible lesions as well. The authors concluded that DWI lesion reversal … Continue reading >>

Cochlear Implants

Waltzman SB, Roland Jr JT, eds. Cochlear Implants. 3rd ed. Thieme; 2014; 268 pgs; 107 illustrations. $109.99

For neuroradiologists who work closely with ENT surgeons, particularly those involved in hearing restoration surgery, parts of this book may be worth reviewing. That is particularly true of Chapter 7, “Principles of Cochlear Implant Imaging”. While neither author of this chapter is a radiologist, they (Drs. Fishman and Herman-Achek) point out in this 25-page chapter the main concepts in preoperative and postoperative imaging. Added to this is a section on MRI compatibility of cochlear implants, in which concerns and questions are … Continue reading >>

Imaging of the Brain

Naidich TP, Castillo M, Cha S, Smirniotopoulos, eds. Imaging of the Brain. Expert Radiology Series. Elsevier Saunders; 2012; 1072 pgs; $315.

There are numerous educational resources available in every radiology subspecialty. They appear on society and academic websites, in journals designed both for original research and review articles, on commercial websites, and, of course, in textbooks. In the latter category, for brain imaging, Osborn’s Brain: Imaging, Pathology, and Anatomy and Diagnostic Imaging: Brain have been the two textbooks that are frequently used as source material. Enter now (published in 2012) the new book Imaging of the Brain, edited … Continue reading >>

Hankey’s Clinical Neurology (2nd Edition) attempts to survey the field of neurology in a single 976–page hard cover book. The editors (Drs. Gorelick, Testai, Hankey, and Wardlaw) have solicited contributions from 46 authors and have produced a book that could be useful for those entering neurology as a resident, or for those in allied fields such as neuroradiology, where an overview is desired. The following topics are covered: neurologic diagnosis, disorders of consciousness, epilepsy, headache, … Continue reading >>

Coiling of Large and Giant Aneurysms: Complications and Long-Term Results of 334 Cases

Fellows’ Journal Club
March 2014

(3 of 3)

The long-term complications of coil treatment of giant intracranial aneurysms were assessed in 334 instances when treatment consisted of only coiling (225), stent-assisted coiling (88), parent vessel occlusion (14), or balloon-assisted coiling (7). The authors concluded that coiling of large and giant aneurysms has reasonable safety profiles with good clinical outcomes, but aneurysm reopening was common. Stent-assisted coiling had lower recurrence, retreatment, and new or recurrent hemorrhage rates with no additional morbidity compared with conventional coiling. Aneurysm size was a major determinant of recanalization, retreatment, new or recurrent hemorrhage, and poor outcome.… Continue reading >>

Complications of Endovascular Treatment for Acute Stroke in the SWIFT Trial with Solitaire and Merci Devices

Fellows’ Journal Club
March 2014

(2 of 3)

The safety of 2 devices to treat acute ischemic stroke was evaluated in 144 patients with special attention paid to complications such as cerebral hemorrhage, SAH, air emboli, vessel dissections, major groin complications, and emboli in new territories. Fewer endovascular complications occurred after treatment with the Solitaire device when compared with the Merci, particularly with respect to symptomatic cerebral hemorrhage.

Abstract

BACKGROUND AND PURPOSE
Treatment of patients with ischemic stroke after endovascular treatment requires in-depth knowledge of complications. The goal of this study was to make endovascular treatment for acute ischemic stroke … Continue reading >>

Pearls and Pitfalls in Head and Neck and Neuroimaging: Variants and Other Difficult Diagnoses

Aygun N, Shah G, Gandhi D.  Pearls and Pitfalls in Head and Neck and Neuroimaging: Variants and Other Difficult Diagnoses. Cambridge University Press; 2014; 498 pgs. 1063 illustrations; $130.00.

The book Pearls and Pitfalls in Head and Neck and Neurimaging: Variants and Other Difficult Diagnoses seeks to evaluate and discuss some of the more difficult interpretative issues in neuroradiology. The authors (Drs. Aygun, Shah, and Gandhi) have selected 106 cases they have deemed to fall into this category of elusive cases. To this reviewer, many of the cases have been properly selected to demonstrate and explain difficulties in interpretation, … Continue reading >>

Appropriate Use of CT Perfusion following Aneurysmal Subarachnoid Hemorrhage: A Bayesian Analysis Approach

Fellows’ Journal Club
March 2014

(1 of 3)

These investigators evaluated the test characteristics of CTP in patients with SAH for detection of delayed cerebral ischemia. Ninety-seven patients were assessed with CTP for ischemia and with DSA for vasospasm. The authors concluded that positive CTP findings identified patients who should be carefully considered for induced hypertension, hypervolemia, and hemodilution and/or intra-arterial therapy while negative CTP findings are useful in guiding a no-treatment decision.

EIC signature

Abstract

BACKGROUND AND PURPOSE
In recent years CTP has been used as a complementary diagnostic tool in the evaluation of delayed cerebral ischemia and vasospasm. Our aim … Continue reading >>
