Morphologic Features and Flow Void Phenomenon in Normal Pressure Hydrocephalus and Other Dementias

Rationale and Objective The aim of this study was to determine the distinctive features of normal-pressure hydrocephalus (NPH) and other dementias on routine T1-weighted and T2-weighted magnetic r...

Matching Breast Masses Depicted on Different Views

Rationale and Objectives Computerized determination of optimal search areas on mammograms for matching breast mass regions depicted on two ipsilateral views remains a challenge for developing mult...

Health Reform

Since last winter, when newly installed President Barack Obama announced that health care reform would be a legislative priority this year, I have intended to write about his concept and legislatio...

Evaluating the Correlation between Film Mammography and MRI for Screening Women with Increased Breast Cancer Risk

Rationale and Objectives Breast magnetic resonance imaging (MRI) is increasingly being added to mammography for screening asymptomatic women at increased risk of breast cancer. Because the directi...

Dual Energy Versus Single Energy MDCT Measurement of Radiation Dose Using Adult Abdominal Imaging Protocols

Rationale and Objectives The aim of this study was to measure the radiation dose of dual-energy and single-energy multidetector computed tomographic (CT) imaging using adult liver, renal, and aort...

Dual-Energy CTA with Bone Removal for Transcranial Arteries

Rationale and Objectives Dual-source computed tomography enables bone removal on computed tomographic angiographic data on the basis of simultaneous dual-energy (DE) acquisition. The aim of this s...

Diffusion-Weighted Imaging Characteristics of Primary Central Nervous System Germinoma with Histopathologic Correlation

Rationale and Objectives The aim of this study was to quantify, using diffusion-weighted magnetic resonance imaging, the microscopic rate of water diffusion in pure germinoma and to determine whet...

Diagnostic Efficacy and Safety of Computed Tomography-Guided Transthoracic Needle Biopsy in Patients with Hematologic Malignancies

Rationale and Objectives The role of transthoracic needle biopsy (TTNB) in patients with hematologic malignancies, particularly in discriminating between malignant and benign etiologies, has not b...

CT-Guided Biopsies of Pancreatic Lesions Impact of Contrast Application Prior to versus Following Needle Placement

Rationale and Objectives Pancreatic lesions are frequently detected in pancreatic phase only, which may lead to false negative findings in CT-guided biopsies. We evaluated the accuracy and complic...

CT and MRI of the Whole Body

CT and MRI of the Whole Body, 5th edition, is an extensive two-volume text covering almost all anatomical sections of radiology, excluding breast imaging. The majority of the material is organized ...
