  • perforation and obstruction of the gastrointestinal tract assessment by Conventional Radiology
    Radiologic Clinics of North America, 1992
    Co-Authors: H A Shaffer
    Abstract:

    Proliferation of new imaging modalities has changed the way abdominal emergencies are evaluated in medical centers where ready access to equipment and personnel make emergency CT, ultrasonography, interventional Radiology, and endoscopy available at all hours of the day or night. In many cases, plain abdominal radiography is being relegated to an ancillary diagnostic role. Conversely, in medical centers with fewer resources, plain radiography remains a primary screening modality for most acute abdominal conditions. Even in centers with unlimited resources, plain films supplemented by gastrointestinal contrast studies as needed remain the modern standard for evaluation of patients who have suspected gastrointestinal perforation and mechanical obstruction. These widely available, easy to perform, and relatively inexpensive procedures are relatively sensitive and specific for evaluation of these problems. It is, therefore, crucial for radiologists to be familiar with the often subtle signs of gastrointestinal perforation and obstruction on plain films. Skills of plain film interpretation should not be permitted to erode in the environment of newer technologies.

  • MR imaging of rheumatoid hand lesions: comparison with Conventional Radiology in 31 patients.
    Clinical and experimental rheumatology, 1992
    Co-Authors: A. Corvetta, Andrea Giovagnoni, Baldelli S, Ercolani P, Giovanni Pomponio, Michele Maria Luchetti, N. Rinaldi, De Nigris E
    Abstract:

    The purpose of this study was to evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) in rheumatoid arthritis (RA) by comparing MRI with Conventional Radiology (CR) findings and by correlating these findings with the clinical and serological profile of the disease. The hands of 31 patients (24 females, 7 males) affected by classical RA were studied using a Magnetom 1.0 T tomograph. Coronal, axial, and/or sagittal SE T1 and GE (FLASH 2D FL: 70 degrees-15 degrees) images were obtained in all patients. Moreover, in 7 patients the MRI study was performed after i.v. injection of Gd DTPA contrast medium (0.2 mM/kg). Ten healthy volunteers were also studied as controls. In all patients a Conventional radiological study was performed as well as a clinical and serological investigation. Two blinded observers evaluated the MRI and CR findings and checked 15 elementary pathological lesions, assigning an MRI and a CR score to each patient. MRI provided higher accuracy than CR in detecting rheumatoid soft tissue changes and minimal skeletal lesions, while the opposite was true for severe skeletal lesions. No correlations emerged between the MRI/CR findings and clinical and serological data. This study suggests that MRI and CR are complementary techniques in the evaluation of the anatomical changes in RA.

  • Preoperative Work-up: Conventional Radiology, Ultrasonography, CT Scan, and MRI
    Updates in Surgery, 2012
    Co-Authors: Stefania Montemezzi, Daniela Cenzi, Massimiliano Motton
    Abstract:

    The optimal assessment and staging of esophageal cancer (EC) is crucial as it has an important impact on patient selection with respect to appropriate treatment (surgery, neo-adjuvant therapy with or without surgery, palliative treatment) [1]. Preoperative evaluation requires knowledge of the esophageal anatomy and of the patterns of tumor spread. As mentioned in Chap. 2, the staging criteria for esophageal cancer include depth of local invasion, nodal involvement, and presence or absence of distant metastases. The various imaging modalities have different strengths and weaknesses in evaluating each of these criteria such that a combined multimodality imaging approach is usually necessary for an optimal assessment [2].
