Diagnostic imaging in a case of choledocholithiasis.

A case of a patient with the diagnosis of a neoformation of the blind intestine is discussed. On CT for staging an image at the level of the intrapancreatic tract of main bile duct of not certain interpretation was visualized. On US choledocholithiasis shown by the typical appearance of a hyperechoic image with posterior shadowing was diagnosed.

A case of pneumonia in a critical patient.

The case of a patient who had recently undergone renal transplantation, and showed symptoms referable to pulmonary infection, is discussed. Chest X-ray showed the presence of bilateral diffuse reticulonodular interstitial involvement. For better characterization HRCT was performed.

Combined diagnostic imaging of a non-traumatic swelling of the popliteal cavity.

A case of a 13-year-old female patient with a non-traumatic hard-elastic swelling in the right popliteal cavity, associated with functional impairment in maximal knee flexion and mild pain, is presented. The combination of clinical and radiologic findings (radiography, CT and MRI) suggested a number of differential diagnoses within bone and soft tissue tumors. The collected diagnostic information did not allow a definitive diagnosis that was established only after biopsy.

Diagnostic approach to a rare case of osteoid osteoma of the astragalus.

A rare case of osteoid osteoma of the ankle of the left foot is discussed. Standard X-ray and MRI were negative. Triphasic bone scintigraphy followed by CT were performed.

Diagnostic imaging in a case of a cystic lesion of the pancreas.

The case of a patient admitted to hospital for symptoms characterized by upper abdominal pain of pancreatic type associated with vomiting, is discussed. MRI was performed. It documented a focal fluid lesion apparently in communication with the dilated main pancreatic duct showing filling defects.

Cine-MR in a patient with suspected normal pressure hydrocephalus.

The case of a patient with predominant short-term memory and CT pattern suggestive of of normal pressure hydrocephalus, is discussed. Clinical and CT findings did not allow to predict the clinical response to a possible ventriculoperitoneal shunt. On MRI more accurate morphological evaluation with cine-MR functional assessment was obtained.

Combined diagnostic imaging of adenomyomatosis of the gallbladder.

The consistency of a request for liver MRI and MR-cholangiopancreatography in a patient with an occasional US-finding of mural thickening of gallbladder fundus > or = 3 mm in size was assessed. The differential US diagnosis in case of focal mural thickening was analyzed in combination with the other findings to justify the radiologicoclinical reliability of the request. Overall, these findings suggested the diagnostic hypothesis of adenomyomatosis, then confirmed by a second level in-depth examination, namely liver MRI and MR-cholangiopancreatography.

Multirow CT angiography of coronary arteries.

The introduction of spiral multislice or multidetector CT (MSCT) has led to significant results in coronary diagnostic imaging. In fact with MSCT, isotropic (cubic voxel) three-dimensional imaging of large volumes (e.g.
