The use of multimodal CT scanning—CT angiography (CTA) and CT perfusion (CTP)—to assess patients with acute stroke seems to have increased rapidly during the past 5 years. This change in clinical practice may affect the speed of acute treatment, methods of triaging to intra-arterial treatment, and the processof subject selection in … Continue reading >>

Neurocysticercosis (NCC) is a common cause of morbidity in manydeveloping countries and a common cause of seizure disorder in children and adults. The 4 stages of NCC are vesicular, vesicular colloidal, granular nodular, and nodular calcified.1 The appearance on MR imaging would depend on the stage of the disease. Most commonly, NCC presents as isohypointense lesions on T1-weighted MR imaging. To our … Continue reading >>

We read with great interest the recent report by Lyders and Morris1 of their case of spinal cord infarction following lumbar transforaminal epidural steroid injection. We would like to highlight the fact that not all corticosteroid preparations are associated with the same risk of embolization.2 There are 4 types of corticosteroid preparations commonly administered in clinical practice: … Continue reading >>

RadCases: Interventional Radiology
Ferral H, Lorenz J. RadCases: Interventional Radiology. Thieme 2010, 224 pages, 493 illustrations, $49.95.
Interventional radiology is a difficult topic to teach and learn. The text RadCases: Interventional Radiology is aimed at preparing radiology residents both for their clinical rotations in IR as well as their dreaded trip to Louisville. This book contains 100 cases and access to 150 more cases online. The cases shown are a mix of what is seen commonly in practice as well as cases a resident might encounter during the ABR examination.
The discussions are brief, almost to a fault, but the bullet points make … Continue reading >>

Molecular Imaging: Radiopharmaceuticals for PET and SPECT
Vallabhajosula S. Molecular Imaging: Radiopharmaceuticals for PET and SPECT. Springer 2009, 372 pages, 221 illustrations, $179.
The field of molecular imaging has been rapidly expanding in the past several years. The ability to gain insights into molecular events non-invasively certainly has profound implications on improving our understanding of different disease processes. It is not surprising that molecular imaging has become a major research area. Numerous probes for PET and SPECT imaging have been developed. Therefore, an overview of the currently available imaging probes will be extremely helpful for researchers as well as clinicians who are interested in the field … Continue reading >>
Tethered Cord Syndrome in Children and Adults
Yamada S, ed. Tethered Cord Syndrome in Children and Adults. 2nd Ed. Thieme Medical Publishers 2010, 288 pages, 184 illustrations, $139.92.
The tethered spinal cord syndrome is now a well-recognized clinical entity. This accomplishment is thanks in large part to many of the authors who have contributed to the second edition of Tethered Cord Syndrome in Children and Adults, edited by Shokei Yamada (Yamada, 2010). The syndrome of progressive clinical deterioration associated with fixation of the spinal cord secondary to a congenital lesion was described nearly 60 years ago (Bassett, 1950). In spite of this, the diagnosis had … Continue reading >>
