Inflammatory lesions of the brainstem: Keys for the diagnosis by MRI.

Objective: To describe the magnetic resonance imaging (MRI) findings for the most common inflammatory and immune-mediated diseases that involve the brainstem.

Conclusion: Inflammatory lesions involving the brainstem are associated with a wide range of autoimmune, infectious, and paraneoplastic syndromes, making the differential diagnosis complex. Being familiar with these entities, their clinical characteristics, and their manifestations on MRI, especially the number of lesions, their shape and extension, and their appearance in different sequences, is useful for orienting the radiological diagnosis.

Evaluation of imaging findings in gastrointestinal anisakiasis in emergency CT and ultrasound.

Background: To assess the frequency of appearance of various signs (isolated and grouped) in emergency imaging tests in patients with anisakiasis, according to the location of gastrointestinal tract involvement.

Methods: Retrospective review by two experienced radiologists of emergency ultrasounds and CTs performed on patients admitted in the Emergency Department of our hospital with later confirmed anisakiasis (2010-2021), assessing the presence of signs suggesting anisakiasis. Calculation of the frequency of appearance according to the gastric or intestinal location, as well as the most common grouped signs.

CT findings for dental disease.

Traumatic and especially inflammatory-infectious dental lesions are very prevalent in our context. Inflammatory-infectious disease is usually discovered incidentally on imaging studies that include the orofacial region. Moreover, these conditions can result in potentially severe complications, so early diagnosis and treatment are important.

Anisakiasis: Imaging findings.

Objective: To review the main findings for anisakiasis in the different imaging tests that can be used to diagnose it, based on studies done at our center.

Conclusion: The presence of Anisakis species in food consumed in Western countries is becoming more common. Patients with anisakiasis present with acute abdomen; there are no specific clinical signs or laboratory findings.

A bibliometric study of the journal Radiología during the period 2010-2019.

Background And Aims: Bibliometrics makes it possible to measure the relative importance of a scientific journal in its field. The current study analyzed the scientific publications in Radiología and the bibliometric parameters of the journal in the period comprising 2010 through 2019.

Materials And Methods: We reviewed the bibliometrics for Radiología through information obtained from three sources: Scopus, the online version of the journal, and the publisher (Elsevier).

Watch and wait approach in rectal cancer: Current controversies and future directions.

According to the main international clinical guidelines, the recommended treatment for locally-advanced rectal cancer is neoadjuvant chemoradiotherapy followed by surgery. However, doubts have been raised about the appropriate definition of clinical complete response (cCR) after neoadjuvant therapy and the role of surgery in patients who achieve a cCR. Surgical resection is associated with significant morbidity and decreased quality of life (QoL), which is especially relevant given the favourable prognosis in this patient subset.

Locoregional staging using magnetic resonance imaging in rectal cancer: influence of diffusion-weighted imaging in the diagnostic accuracy.

Objective: To assess whether the accuracy in locoregional staging using magnetic resonance imaging (MRI) in rectal cancer (primary or post-chemoradiotherapy) improves by adding diffusion-weighted imaging, according to the radiologist's degree of experience.

Method: Retrospective study on 100 MRI records (1.5 T, 2011-2016) from patients with rectal cancer (reference standard: histology of surgical specimens).

Primary and post-chemoradiotherapy MRI detection of extramural venous invasion in rectal cancer: the role of diffusion-weighted imaging.

Objective: To assess the added value of diffusion-weighted imaging (DWI) to high-resolution T2-weighted sequences (HRT2w) in MRI detection of extramural venous infiltration (EMVI), according to the previous experience of radiologists.

Methods: A cross-sectional study of a retrospective database including 1.5 T MRI records from 100 patients with biopsy-proven rectal cancer (2011-2016; 75 male/25 female, average 63 y/o), which included primary staging (54) and post-chemoradiotherapy follow-up MRIs (46).

Doctoral theses: a survival guide for radiologists.

Nowadays, there are, surprisingly, many opportunities for research in the field of radiology, and these are accessible at any level. Thanks to radiological information systems and picture archiving and communication systems (PACS), a huge number of images and cases are available. Nevertheless, the daily workload and the lack of resources sometimes limit the advance of radiologic research.

Nodal staging in the rectal cancer follow-up MRI after chemoradiotherapy: use of morphology, size, and diffusion criteria.

Aim: To analyse changes in post-neoadjuvant follow-up magnetic resonance imaging (MRI) staging accuracy for malignant adenopathies in rectal cancer, by comparing size criteria with morphological criteria using high-resolution T2-weighted sequences, as well as variations when adding diffusion-weighted imaging.

Methods And Materials: The present study was a cross-sectional study of a database including 46 1.5-T MRI examinations (2011-2016) from patients with biopsy-proven rectal cancer and chemoradiotherapy treatment before surgery.

Primary and post-chemoradiotherapy staging using MRI in rectal cancer: the role of diffusion imaging in the assessment of perirectal infiltration.

Purpose: To analyze changes in MRI diagnostic accuracy in main rectal tumor (T) evaluation resulting from the use of diffusion-weighted imaging (DWI), according to the degree of experience of the radiologist.

Methods: This is a cross-sectional study of a database including one hundred 1.5 T MRI records (2011-2016) from patients with biopsy-proven rectal cancer, including primary staging and post-chemoradiotherapy follow-up.

Focused assessment with sonography for trauma (FAST) versus multidetector computed tomography in hemodynamically unstable emergency patients.

This critically appraised topic (CAT) study aims to evaluate the quality and extent of the scientific evidence that supports the use of focused assessment with sonography for trauma (FAST) versus multidetector computed tomography (MDCT) in hemodynamically unstable trauma patients in the emergency room. An efficient search of the literature yielded several recent articles with a high level of evidence. The CAT study concludes that FAST is an acceptable initial imaging test in hemodynamically unstable patients, although its performance is limited in certain circumstances.

[Are urgent imaging tests indicated in the management of acute pancreatitis?].

Acute pancreatitis is a common emergency within abdominal disease. It is accepted that two of three conditions must be fulfilled for its diagnosis: characteristic clinical presentation, characteristic laboratory findings, and/or characteristic diagnostic imaging findings. The first two conditions are the most often used, probably for reasons of efficiency and frequency.

Two types of presentation of pulmonary inflammatory pseudotumors.

Inflammatory pseudotumors are a relatively uncommon pathology of uncertain etiology, generally considered to be reactive in origin. They may be observed in different locations as single or multiple masses. One of the possible forms of presentation is intrapulmonary.
