Imaging of Blunt and Penetrating Craniocervical Arterial Injuries
Both blunt and penetrating craniocervical arterial injuries are potentially devastating, leading to either death or cerebral infarction. In contemporary trauma care, essentially the same imaging tools are used to diagnose each subset of injury. However, given different mechanisms of injury and clinical management approaches, blunt and penetrating cervical injuries merit separate discussion. From here on, the authors will discuss blunt and penetrating cervical vascular injuries and the role of diagnostic imaging in evaluating those patients who may have them.

Letter from the Editor: Patient Protection and Affordable Care Act
The Patient Protection and Affordable Care Act (PPACA, also referred to as the Affordable Care Act, or ObamaCare) was signed into law on March 23, 2010. It was enacted to increase the quality and affordability of health insurance, lower the uninsured rate, and reduce the costs of healthcare for individuals and the government. The creation of state and federal health insurance marketplaces has been a dominant feature of the PPACA, even though only a small percentage of people obtain health insurance through the marketplace.

Pitfalls in Imaging of Cervical Cancer
Worldwide, cervical cancer is the second most common cancer in women and is the most common cause of cancer death in women less than 35 years of age (1–5). Early detection with the Papanicolaou smear and active screening has resulted in a marked decrease in the incidence of cervical cancer in developed regions of the world; however, even in developed countries, 38% of women with cervical cancer die due to their disease (1,3–6). In the contemporary management of women with cervical cancer, pre-treatment imaging with computed tomography (CT), magnetic resonance (MR) imaging and positron emission tomography (PET)/CT is cr...

Letter from the Guest Editors: Pitfalls in Abdominal Imaging: Part 1
We continue the theme of addressing technical and interpretive issues that can present pitfalls in imaging. This issue and the next explore the problems that imagers may encounter when evaluating the abdomen and pelvis for varying pathologies. The authors, all experts all in the subjects they write about, illuminate the many subtleties that are crucial in assessing imaging studies in the abdomen and pelvis; awareness of these nuances may help avoid the pitfalls that can lead to missed, erroneous, or delayed diagnoses in the patients entrusted to our care.

Pitfalls in Imaging After Gastrointestinal Surgery
A postoperative abdomen can be extremely challenging on cross-sectional imaging. Knowledge of normal postoperative anatomy1-6 and pitfalls2-5 is important for accurately diagnosing complications. There is an exhaustive list of abdominal surgeries; however, this article gives a general account of some of the pitfalls seen in abdominal surgeries. Before discussion of the pitfalls, we shall discuss the technique used for computed tomography (CT) scanning in the postoperative period and common surgical principles used.

Pitfalls in imaging after GI surgery
Following abdominal surgery, interpretation of CT and MRI scans of the abdomen can be confusing. It is important to be aware of the variety of appearances that can be encountered. There is usually a surgical explanation which is accurately identified with close collaboration with surgical colleagues. An appreciation of the normal post-operative appearances allows recognition of the abnormal. Potential pitfalls in interpretation are discussed in relation to common abdominal surgeries.

Pitfalls in Imaging For Advanced Ovarian Cancer
Ovarian cancer is a relatively rare cancer, but it has a severe prognosis, mainly because it is often discovered at an advanced stage.1 Most ovarian cancers (95%) are epithelial and therefore appear to the radiologist as mixed cystic and solid masses. Among these epithelial cancers, 70% are high-grade serous cystadenocarcinomas. (Source: Seminars in Roentgenology)

Common Technical and Anatomical Pitfalls in the Evaluation of Multiparametric Prostate Magnetic Resonance Imaging
Multiparametric magnetic resonance imaging (MRI) is the single most versatile imaging assessment of the prostate, which is useful in delineating local soft tissue anatomy and in tumor visualization while providing superior soft tissue resolution. Multiparametric MRI readily detects extracapsular and seminal vesicle invasion, both of which are important staging and prognosticating factors.1-3 MRI is also helpful in assisting in surgical planning, especially if a neurovascular bundle–sparing technique is considered.

Pitfalls in Pancreatic Imaging
The use of multi detector computed tomography (MDCT) and magnetic resonance imaging (MRI), with imaging protocols optimized for imaging of the pancreas have improved the localization as well as the detection and characterization of pancreatic lesions. Although the typical radiologic appearances of common pancreatic lesions is well known; there are several potential pitfalls that can be encountered in pancreatic imaging such as pancreatic anatomic variants mimicking pancreatic lesions, inflammatory conditions mimicking malignancy, atypical radiologic appearance of pancreatic adenocarcinoma and cystic pancreatic lesions and ...

Pitfalls in Adrenal Imaging
With the widespread dissemination of cross-sectional imaging, incidental adrenal nodules are frequently encountered in clinical practice. While most incidental adrenal nodules are benign adrenal adenomas, the incidence of malignancy increases in patients with a personal history of malignancy and in adrenal lesions greater than 4 cm in size.1 The imaging diagnosis of adrenal nodules is therefore clinically important. The purpose of this review article is to highlight common and uncommon pitfalls that may be encountered when evaluating the adrenal glands in clinical practice to help guide radiologists to provide more accurat...

Mimics of Hepatic Neoplasms
The normal liver receives a dual blood supply from the hepatic artery and the portal vein, each supplying approximately 25% and 75% of blood volume respectively.1 As a result, there is low enhancement of the normal liver parenchyma during the arterial phase as the contrast transported by the hepatic artery is diluted by a ratio of 4:1 by unopacified portal venous blood. Note that hepatic neoplasms are usually predominantly supplied by the hepatic artery. This distinction is the basis for the multiphase contrast enhanced liver protocol for computed tomography (CT) and MRI. (Source: Seminars in Roentgenology)
