MRI rare finding: Absence of the left liver lobe.

We report a rare case of left liver lobe absence in an 80-year-old male patient discovered during an MRI scan. The main imaging features of this condition are briefly reviewed, together with its pathogenesis and the most common associations and differential diagnoses.

The key role of the radiologist in the management of polytrauma patients: indications for MDCT imaging in emergency radiology.

Trauma causes greater losses of life years and it is the most common cause of death for people under the age of 45. Time is one of the most relevant factors for the survival of injured patients, particularly the time elapsed from trauma until the resuscitation procedures. As a member of the trauma team, the radiologist contributes to the rapid diagnosis of traumatic disorders, with appropriate imaging modalities.

Rectal villous tumours: MR features and correlation with TRUS in the preoperative evaluation.

Aim: The aim of this study was to assess the clinical relevance of MR and transrectal ultrasonography (TRUS) imaging of rectal villous tumours to elucidate the correlation between imaging results and specific histopathological tumour features, such as tumour size (T) and lymph node involvement (N), in order to establish the better technique for the pre-surgical patient evaluation.

Patients And Methods: 23 cases of villous tumours of the rectum were studied with phased-array MR and TRUS. All patients underwent either surgical or endoscopic treatment.

Comparison among preoperative single-slice CT and multi-slice CT in simple, closed loop and strangulating bowel obstruction.

Background/aims: The aim of this study is to compare preoperative single-slice CT (SSCT) and multislice-CT (MSCT) accuracy in the evaluation of patients with bowel obstruction and intestinal necrosis.

Methodology: 64 patients were enrolled. We analyzed the SSCT scans of 30 patients and the MSCT scans of 34 patients with clinical and abdominal plain film evidence of bowel obstruction.

Preoperative locoregional staging of rectal carcinoma: comparison of MR, TRUS and Multislice CT. Personal experience.

Purpose: The aim of this study was to measure the sensitivity and clinical indications of Magnetic Resonance (MR) as compared to Transrectal Ultrasonography (TRUS) and spiral Computed Tomography (CT) in the preoperative staging and evaluation of rectal carcinoma.

Materials And Methods: Twenty patients with histologically proven rectal carcinoma were examined with phased-array coil MRI. We used T1 and T2, spin-echo, turbo-spin-echo, flash2D sequences with and without fat suppression; FOV 180-280; 4-6 mm slice thickness; i.

A case of duodenal duplication in an adult.

We report a rare case of duodenal duplication, manifested in an adult with aspecific symptoms, whose diagnosis was possible with ultrasound at the beginning and then with gastrointestinal barium study, endoscopic ultrasonography and contrast enhanced CT scan; it was confirmed surgically.

Gray-scale and color Doppler findings in bilateral internal jugular vein thrombosis caused by anaplastic carcinoma of the thyroid.

Bilateral internal jugular vein thrombosis is a rare complication of thyroid cancer. The most common manifestation of this condition is superior vena cava syndrome. We report the sonographic findings in a case of bilateral internal jugular vein thrombosis with mild symptoms.

Preoperative evaluation of primary hyperparathyroidism: role of diagnostic imaging.

This study analyses the diagnostic value of preoperative diagnostic imaging examinations in the identification and location of pathological parathyroid glands. We examined 77 patients with primary hyperparathyroidism using ultrasonography of the neck and Tc99m-MIBI scintigraphy for preoperative assessment purposes. All patients underwent surgical treatment.
