Computed Tomography of Internal Hernias Following Laparoscopic Roux-en-Y Gastric Bypass Surgery
Publication date: April 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 2Author(s): Yoan K. Kagoma, Gabriela GayerInternal hernia in the postoperative laparoscopic Roux-en-Y patient is a diagnosis associated with significant morbidity and risk of death. The radiologist plays an instrumental role in workup of this patient group; however, the imaging assessment of these patients is not straightforward given their complex postsurgical anatomy. Multiple radiologic signs of internal hernia have been studied in the literature. This review article presents these signs with representative cases as well as a summar...

Imaging of Oncologic Emergencies
Publication date: April 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 2Author(s): Francesca Iacobellis, Alessandra Perillo, Isabella Iadevito, Michela Tanga, Luigia Romano, Roberto Grassi, Refky Nicola, Mariano ScaglioneOncologic emergencies can be either the result of the primary tumor, its metastasis, a paraneoplastic syndrome or reaction to the chemotherapy. Imaging plays a crucial role in ensuring a prompt diagnosis as well as assisting in the therapeutic management. In this article, we discuss the common thoracic and abdominal oncological emergencies that may be encountered in an emergency departmen...

Pneumatosis From Esophagus to Rectum: A Comprehensive Review Focusing on Clinico-Radiological Differentiation Between Benign and Life-Threatening Causes
Publication date: April 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 2Author(s): Ulysses S. Torres, Camila D.F.M. Fortes, Priscila S. Salvadori, Dario A. Tiferes, Giuseppe D′IppolitoPneumatosis of the alimentary tract may occur from the esophagus to rectum as a result of a wide spectrum of conditions that range from benign to life-threatening. Although distinguishing between these 2 groups is of paramount importance for an appropriate clinical management, it still remains a challenge for the radiologist in the daily practice. In the light of the current literature, we provide in the present article a ...

Imaging of Spine Fractures With Emphasis on the Craniocervical Junction
Publication date: Available online 16 April 2018Source: Seminars in Ultrasound, CT and MRIAuthor(s): Gabriela Santos-Nunez, Hao S. Lo, Hemang Kotecha, Joe Jose, Aly AbayazeedSpinal cord injury often times is a catastrophic result of trauma. Delay in diagnosis may result in increased morbidity and mortality. Cross-sectional imaging is now increasingly used as a first-line diagnostic modality in the setting of trauma for recognition of spine fractures and ligamentous injuries that might be missed on routine radiographs. The learning objectives of this article are to review the anatomy of the spine and understand the mechanis...

Soft Tissue Injuries of the Finger and Thumb
Publication date: Available online 16 April 2018Source: Seminars in Ultrasound, CT and MRIAuthor(s): Juliann Giese, Christopher CernigliaSoft tissue digital injury of the hand is a common presenting complaint in the emergency setting. Although initial work-up requires physical examination and radiographs, many of these entities may be radiographically occult and solely appreciated on ultrasound (US) or magnetic resonance imaging (MRI). If undiagnosed, these conditions may lead to sequela of untreated disease including early osteoarthritis, pain, permanent deformity, and immobility. Soft tissue finger injuries that may not ...

Immunotherapy in Lung Cancer and the Role of Imaging
Publication date: June 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 3Author(s): Brett W. CarterLung cancer is the leading cause of cancer-related mortality and accounts for more deaths than breast, prostate, and colon cancers combined. Traditionally, treatment options have included surgery, chemotherapy, and radiation therapy. Continual advances in the characterization of lung cancer have resulted in the development of effective immunotherapies. These agents help the immune system recognize tumors as foreign, stimulate the immune system, and relieve the inhibition that allows the growth and spread of ca...

Imaging on Lung Cancer and Treatment with Targeted Therapy
Publication date: June 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 3Author(s): Girish S. Shroff, Marcelo F. Benveniste, Patricia M. de Groot, Brett W. Carter, Carol C. Wu, Chitra Viswanathan, Mylene T. TruongThe identification of genetic mutations known as oncogenic driver mutations that lead to the growth and survival of cancer cells has been an important advance in the field of oncology. Treatment in advanced non–small-cell lung cancer (NSCLC) has transitioned from a more general approach to a more personalized approach based on genetic mutations of the cancer itself. Common mutations detected in p...

Carter, Ana Paula A. Benveniste, Edith M. MaromRadiation therapy is an important modality in the treatment of patients with lung cancer. Recent advances in delivering radiotherapy were designed to improve loco-regional tumor control by focusing higher doses on the tumor. More sophisticated techniques in treatment planning include 3-dimensional conformal radiation therapy, intensity-modulated radiotherapy, stereotactic body radiothera...

Postoperative Imaging and Complications in Resection of Lung Cancer
Publication date: June 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 3Author(s): Patricia M. de Groot, Mylene T. Truong, Myrna C.B. GodoySurgical resection offers the best hope of cure for patients with operable early-stage lung cancer. Wedge resection, segmentectomy, lobectomy, or pneumonectomy may be performed depending on the size and location of the tumor. Radiologists must be familiar with the types of surgical resection utilized in the treatment of lung carcinoma and with their normal and abnormal postsurgical appearance on imaging studies. Prompt identification of postoperative complications on im...
