Lung cancer is a heterogenous disease with 2 main subtypes: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Early-stage NSCLC is managed primarily by surgical resection, with adjuvant chemotherapy for selected patients with stage IB, II, and III disease. ⋯ Advanced NSCLC remains an incurable disease. Further advances will rely on improvements in understanding of the molecular events driving the malignant phenotype and the development of novel, targeted therapeutic strategies.

Imaging assessment of the postoperative spine is complex and depends on many factors. Postoperative imaging studies evaluate the position of implants, adequacy of decompression, fusion status, and potential complications. This article provides a review of various imaging techniques, with their advantages and disadvantages, for the evaluation of the postoperative spine. It also gives an overview of normal and abnormal postoperative appearances of the spine as seen via various modalities, with an emphasis on postoperative complications.

This article reviews the imaging and relevant clinical details of infection of the extradural spine. Spine infections are increasing in incidence and in frequency of diagnosis. They are clinically important despite their relative rarity, because they may be life-threatening, and because early diagnosis leads to improved outcomes. ⋯ Nonpyogenic, granulomatous infections are also addressed. Magnetic resonance imaging is emphasized. The radiologist's role in performing minimally invasive sampling procedures is highlighted.

ReviewLumbar diskogenic pain, provocation diskography, and imaging correlates.
Diskogenic pain refers to pain mediated by the intrinsic innervation of the intervertebral disk. It is experienced as pain centered at the symptomatic spine segment (axial pain) without radicular features or radiculopathy. ⋯ This article reviews diskogenic pain, the history of provocation diskography, and its current use in the diagnosis of lumbar diskogenic pain. The extensive literature describing imaging features which may predict a positive diskogram, and allow non-invasive diagnosis of diskogenic pain, is examined.

Spinal dural arterial venous fistulas (SDAVFs) are the most common vascular malformation of the spine. They typically present in elderly men with slowly progressive myelopathic symptoms. ⋯ Radiologists should be familiar with the imaging features of this entity, with the surgical and angiographic interventions, and with the expected postprocedural radiographic appearance. This article reviews spinal vascular anatomy, the radiographic appearances of SDAVF, techniques for finding the SDAVF, clinical presentations, treatment options, and postprocedural radiographic appearances of the spinal cord.
