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.

Picture archiving and communication in radiology.

After over 80 years of exclusive archiving of radiologic films, at present, in Radiology, digital archiving is increasingly gaining ground. Digital archiving allows a considerable reduction in costs and space saving, but most importantly, immediate or remote consultation of all examinations and reports in the hospital clinical wards, is feasible. The RIS system, in this case, is the starting point of the process of electronic archiving which however is the task of PACS.

Information systems in the management of the radiology department.

Clinical, organizational and administrative service improvement has always been the primary aim of a radiology information system. Studies carried out at Massachusets General Hospital in the late sixties identified two "bottlenecks" in the Departments of Diagnostic Imaging: the planning of examinations and the management of picture archiving. Therefore, the information system started to be viewed as a potential tool for the solution of these problems.

Diagnostic imaging of neurogenic bladder.

Correct radiologic diagnosis of neurogenic bladder is mainly based on morphofunctional information derived from voiding cystourethrography. This examination allows the evaluation of the bladder morphology, the degree of filling, and the validity of muscular contraction. Indications on the bladder neck, striated sphincter function and urethral morphology are also provided.

The neurogenic bladder: anatomy and neurophysiology.

Micturition disorders secondary to alterations of complex neural controls do not represent a separate, typified condition but frequently they are symptoms of more complex diseases. Unfortunately, they are often misunderstood leading to severe damages to the patient. In diagnostic imaging of neural alterations of micturition, a major role is played by voiding cystourethrography for its contribution to both the morphologic and functional aspects.
