Airway wall thickness and airflow limitations in asthma assessed in quantitative computed tomography.

Background: Asthma is a frequent chronic disease of the airways. In spite of the fact that symptoms of asthma are well known, the pathogenesis has not yet been fully understood. Quantitative computed tomography (qCT) of the lung allows for the measurment of a set of parameters.

Application of the apparent diffusion coefficient in magnetic resonance imaging in an assessment of the early response to treatment in Hodgkin's and non-Hodgkin's lymphoma - pilot study.

Purpose: Lymphoproliferative neoplasms are the largest and most frequently diagnosed entities in the group of haematological malignancies. The aim of the study was to assess whether apparent diffusion coefficient (ADC) measured on the first day of the second cycle of chemotherapy could be a predictor of prognosis and of the final treatment's outcome.

Material And Methods: The study included 27 patients with diagnosed Hodgkin's and non-Hodgkin's lymphoma, who had magnetic resonance (MR) performed with diffusion weighted imaging/apparent diffusion coefficient (DWI/ADC) before and on the first day of the second cycle of chemotherapy.

Radiomics - the value of the numbers in present and future radiology.

Radiomics is a new concept that has been functioning in medicine for only a few years. This idea, created recently, relies on processing innumerable quantities of metadata acquired from every examination, followed by extraction thereof from relevant imaging examinations, such as computer tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET) images, by means of appropriate created algorithms. The extracted results have great potential and broad possibilities of application.

Which organ should be considered a reference in diffusion weighted imaging of the abdomen?: The reproducibility of ADC measurements of the spleen and the renal cortex on a 1.5T MR.

Background: Diffusion weighted imaging (DWI) is a useful tool for the evaluation of focal lesions in the liver or kidneys, as well as for the diagnosis and assessment of the liver fibrosis process. Some reports show that the spleen and kidneys may serve as reference organs in the staging of liver fibrosis or the evaluation of focal liver lesions.

Objectives: The aim of the study was to determine whether the spleen and renal cortex can be used as reference organs in the DWI technique.

Low-dose computed tomography in assessment of pulmonary abnormalities in children with febrile neutropenia suffering from malignant diseases.

Background: Management of febrile neutropenia in pediatric patients is challenging. Chest X-ray and CT scan help to identify infective foci; however, exposure to radiation is a risk factor for development of secondary cancer. For this reason, attention is paid to reducing radiation exposure.

Unusual Use of Gd-EOB-DTPA in MRCP in Order to Reveal the Source of Bile Leakage in a Patient with Neuroendocrine Tumor - Case Report.

Background: MRCP is the method of choice in diagnosing pathologies of the biliary system. One of them is bile fistulae. They are uncommon but tend to cause many diagnostic problems.

Modified sonoelastographic scale score for lymph node assessment in lymphoma - a preliminary report.

Unlabelled: Elastography is a new method of assessment of lymph node consistency. The majority of papers focus on metastases detection of head and neck or breast tumors. The typical desmoplastic reaction in connective tissue stroma in cancer, which is responsible for tissue's hardening, is seen in lymphoma less frequently.

Ultrasound Elastography--Review of Techniques and Its Clinical Applications in Pediatrics--Part 1.

Sonoelastography is a novel technique that uses ultrasound waves to assess the elasticity of tissues noninvasively. It provides an ultrasound-based method to detect and display the relative stiffness of tissue. The main principle of sonoelastography is the measurement of tissue distortion in response to external compression.

A Rare Case of Aggressive Fibromatosis Infiltrating Dorsal Muscles in a 6-Year-Old Patient - CT, MRI and Elastography Evaluation.

Background: The term fibromatosis or desmoid tumor refers to a group of benign fibrous growths without metastatic potential but with a significant risk of local recurrence. These lesions typically present infiltrative growth pattern with local invasion of adjacent tissues. This tendency is the reason for a relatively high rate of local recurrence, even after surgical removal.

Ultrasonography in the diagnosis of hemorrhagic cystitis - a complication of bone marrow transplantation in pediatric oncology patients.

Objective: The aim of this study was to evaluate the usefulness of ultrasonography in the diagnosis of hemorrhagic cystitis following bone marrow transplantation in children.

Material And Methods: The study involved an analysis of clinical material and the results of imaging tests performed in 334 patients who underwent hematopoietic cell transplantation. Ultrasonographic findings in 42 patients with hemorrhagic cystitis were analyzed in detail.
