Abstract	The radiologist can play a key role in diagnosis and management of many of the infectious, inflammatory, and neoplastic processes that affect patients after liver transplantation. Familiarity and skill with the full range of diagnostic and interventional tools are essential for radiologists dealing with transplant patients, even outside the medical centers where the transplantation takes place.

Abstract	Cancer is one of the leading causes of morbidity and mortality in developed countries such as the United States. Complex clinical decisions about treatment of oncologic patients are largely guided by imaging findings, among other factors. Most radiologic procedures map the anatomy and morphology of tumors with little or no information about their metabolism. Positron emission tomography (PET) performed with 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) has proved valuable in providing important tumor-related qualitative and quantitative metabolic information that is critical to diagnosis and follow-up. PET-computed tomography (CT) is a unique combination of the cross-sectional anatomic information provided by CT and the metabolic information provided by PET, which are acquired during a single examination and fused. FDG PET-CT offers several advantages over PET alone; the most important is the ability to accurately localize increased FDG activity to specific normal or abnormal anatomic locations, which may be difficult or even impossible with PET alone. Understanding the principles of FDG PET-CT and the optimal scanning techniques and recognizing the potential pitfalls and limitations are important for advantageous use of this imaging modality.

Abstract	Objective: The purpose of our study is to describe a new imaging finding observed on contrast-enhanced MDCT of discontinuity in the intimomedial flap seen with aortic dissection that may identify the level of intimomedial entrance tear and distinguish true from false lumen. Conclusion: Direct visualization of an intimomedial rupture on MDCT is a valuable cross-sectional imaging sign indicating direction of the intimomedial entrance tear from true to false lumen in cases of aortic dissection. The presence of this finding enables reliable distinction of the true lumen, where the tear is broad-based and erupts into the false lumen, which receives the evaginating tear. Improved scanning techniques through MDCT may have enabled recognition of this relatively infrequent, yet highly specific, finding.

Abstract	Fetus in fetu is an extremely rare entity and refers to the growth of a "parasitic" twin within a more mature fetus due to its inclusion within cells of the blastocyst. The presence of a vertebral column is considered essential for the diagnosis of a fetus in fetu. The retroperitoneum is the most common location for a fetus in fetu and its location in the mouth is rare. We report a case of oropharyngeal mass detected on antenatal sonography with imaging features consistent with a fetus in fetu. Complete surgical removal of the mass was aided by imaging. Follow-up of these patients is recommended to detect the rare incidence of malignant degeneration.

Abstract	A 55-yr-old female presented with a mass near the left adrenal gland detected on a CT scan performed for breast cancer staging. A CT-guided fine-needle aspiration (FNA) was performed and showed scattered ciliated cells, compatible with benign respiratory-type epithelial cells. CT-guided needle biopsy also showed fibrocollagenous and fibroadipose connective tissue with focal respiratory type epithelium with subepithelial mucus glands. A final diagnosis of extralobar pulmonary sequestration (ELS) was rendered after surgical resection. This uncommon benign congenital malformation should be considered in the differential diagnosis of FNA of an intraabdominal mass in an adult.

Abstract	Objective: The objective of our study was to determine whether a method could be found to reduce iatrogenic radicular pain during needle placement in lumbar diskography. Materials and methods: After obtaining permission from the institutional review board at the University of Pittsburgh Medical Center, we conducted a study using medical records and existing data that were recorded for quality control during lumbar diskography. A coaxial technique was being used for lumbar diskography. We evaluated data for 71 intervertebral disks in 26 patients in which the needle placement was randomly high (superior) or low (inferior), and the associated pain response during needle placement was recorded. In an attempt to minimize iatrogenic pain during needle placement, we identified a potentially "safe window" for needle placement on MRI of the lumbar spine. On oblique fluoroscopy of the lumbar spine, the safe window is a triangle formed by the superior articular facet medially, the superior endplate of the lower vertebra inferiorly, and an imaginary line joining the tip of the superior articular facet and the superolateral tip of the vertebral body. This safe window was then used for needle placement in another 73 intervertebral disks in 27 patients. Pain response to needle placement was recorded for quality control, and the medical records were retrospectively compared with the initial 71 intervertebral disks in which needle placement was random. Results: In the initial group with random needle placement, lower extremity radicular pain occurred in 13 (18.3%) of 71 intervertebral disks with superior needle placement and in 23 (32.4%) of 71 intervertebral disks with inferior needle placement (total, 50.7%). The pain responses of the superior and inferior groups were not significantly different (p = 0.27). On MRI, the average distances between the nerve ganglion-fascicle-rami and the superior articular facets at the superior disk level were 1.1, 1.4, and 2.5 mm at L3-L4, L4-L5, and L5-S1, respectively. The average distances between the nerve ganglion-fascicle-rami and the superior articular facets at the inferior disk level were 3.0, 3.6, and 6.6 mm at L3-L4, L4-L5, and L5-S1, respectively. When the safe window was used, only five (6.8%) of 73 patients reported radicular pain. The decrease in radicular pain between the two groups was significant (p < 0.001). Conclusion: Iatrogenic lower extremity radicular pain is common during random needle placement at lumbar diskography. High or low needle placement in the intervertebral disk could not predict whether radicular pain would be averted. We identified a safe window that can be used for needle placement during lumbar diskography to minimize iatrogenic lower extremity radicular pain and thereby improve the reliability of the test.
