      Kapoor, Neena; Shinagare, Atul B.; Jagannathan, Jyothi P.; Shah, Shaan H.; Krajewski, Katherine M.; Hornick, Jason L.; Ramaiya, Nikhil H. (Versita, Warsaw, 2014)
      Background: The aim of the study was to evaluate the clinical and imaging features of extraskeletal myxoid chondrosarcoma (EMC) including initial presentation, recurrence, and metastases. Patients and methods. In this ...

    • Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements 

      Ulano, Adam; Bredella, Miriam A.; Burke, Patrick J; Chebib, Ivan Adel; Simeone, Frank J; Huang, Ambrose J.; Torriani, Martin P.; Chang, Connie Y. (American Roentgen Ray Society, 2016)
      Purpose: To determine if CT density thresholds of osteoblastic bone lesions can be used to distinguish untreated osteoblastic metastases from enostoses. Materials and Methods: The study group comprised 62 patients (37 ...

    • Lacrimal gland abscess presenting with preseptal cellulitis depicted on CT 

      Ginat, Daniel Thomas; Glass, Lora Rabin Dagi; Yanoga, Fatoumata; Lee, Nahyoung Grace; Freitag, Suzanne K. (Springer Berlin Heidelberg, 2016)
      Background: Pyogenic lacrimal gland abscesses are uncommon and thus may not be immediately clinically recognized without a high index of suspicion. Findings: We present two patients with preseptal cellulitis and characteristic ...

    • Omental Cakes: Unusual Aetiologies and CT Appearances 

      Mamlouk, Mark Daniel; vanSonnenberg, Eric; Shankar, Sridhar; Silverman, Stuart George (Springer-Verlag, 2011)
      Background: Omental cakes typically are associated with ovarian carcinoma, as this is the most common malignant aetiology. Nonetheless, numerous other neoplasms, as well as infectious and benign processes, can produce ...

    • Radiogenomics of clear cell renal cell carcinoma: preliminary findings of The Cancer Genome Atlas–Renal Cell Carcinoma (TCGA–RCC) Imaging Research Group

    • Systemic treatment in breast cancer: a primer for radiologists 

      Michaels, Aya Y.; Keraliya, Abhishek R.; Tirumani, Sree Harsha; Shinagare, Atul B.; Ramaiya, Nikhil H. (Springer Berlin Heidelberg, 2015)
      Abstract Cytotoxic chemotherapy, hormonal therapy and molecular targeted therapy are the three major classes of drugs used to treat breast cancer. Imaging modalities such as computed tomography (CT), magnetic resonance ...

    • T-Cell Non-Hodgkin Lymphomas: Spectrum of Disease and the Role of Imaging in the Management of Common Subtypes 

      Park, Hye Sun; McIntosh, Lacey; Braschi-Amirfarzan, Marta; Shinagare, Atul B.; Krajewski, Katherine M. (The Korean Society of Radiology, 2017)
      T-cell non-Hodgkin lymphomas (NHLs) are biologically diverse, uncommon malignancies characterized by a spectrum of imaging findings according to subtype. The purpose of this review is to describe the common subtypes of ...
