Texture Analysis in Uterine Cervix Carcinoma: Primary Tumour and Lymph Node Assessment.

The conventional magnetic resonance imaging (MRI) evaluation and staging of cervical cancer encounters several pitfalls, partially due to subjective evaluations of medical images. Fifty-six patients with histologically proven cervical malignancies (squamous cell carcinomas, = 42; adenocarcinomas, = 14) who underwent pre-treatment MRI examinations were retrospectively included. The lymph node status (non-metastatic lymph nodes, = 39; metastatic lymph nodes, = 17) was assessed using pathological and imaging findings.

Computer Tomography in the Diagnosis of Ovarian Cysts: The Role of Fluid Attenuation Values.

Pathological analysis of ovarian cysts shows specific fluid characteristics that cannot be standardly evaluated on computer tomography (CT) examinations. This study aimed to assess the ovarian cysts' fluid attenuation values on the native (Np), arterial (Ap), and venous (Vp) contrast phases of seventy patients with ovarian cysts who underwent CT examinations and were retrospectively included in this study. Patients were divided according to their final diagnosis into the benign group ( = 32) and malignant group ( = 38; of which 27 were primary and 11 were secondary lesions).

The utility of texture-based classification of different types of ascites on magnetic resonance.

Purpose: To quantify specific characteristics of different types of ascitic fluid on magnetic resonance (MR) images and to determine their utility for computer-assisted lesion classification.

Methods: The MR images of 48 patients with intra-abdominal fluid were retrospectively analyzed. Patients were grouped according to the underlying disease and pathological outcomes.

Is there a place for F18-FDG PET/CT in the diagnosis of primary breast cancer?

Purpose: With the improvement of techniques and the update of diagnostic protocols in breast cancer, modern imaging proves to be effective in the diagnosis of this pathology, as well as in its prognosis. This study aimed to evaluate the effectiveness of these modern imaging techniques through a systematic assessment of the most recent studies.

Methods: A PUBMED search, using certain key combinations ("breast cancer", "F18 FDG PET-CT", "MRI", "staging", "diagnosis") and some inclusion and exclusion criteria, yielded 24 articles published during 2014-2018.

A malignant phyllodes tumor with liposarcomatous differentiation case with 3-year follow-up.

Phyllodes tumors (PTs) are a group of rarely breast tumors of fibro-epithelial origin, counting for about 1% of the breast malignancies divided, based on histological features, in benign, borderline and malignant neoplasms, arising most of them in women in their 40's. Among this complex group of tumors, the liposarcomatous differentiation is an even more rare lesion, counting for about 0.3% of all primary sarcomas of the breast.
