To the best of our knowledge, there is little available organized advice for diagnostic radiology residency program directors and their programs regarding resident recruitment. We are a group of current and former program directors who are current vice chairs for education and continue to advise and to mentor many educators. We have constructed this article along the yearly schedule of trainee recruitment, including an application review, interviews, and troublesome trends that we have observed.

Objective: The new 2013/59 EURATOM Directive (ED) demands dosimetric optimisation procedures without undue delay. The aim of this study was to optimise paediatric conventional radiology exams applying the ED without compromising the clinical diagnosis. METHODS: Automatic dose management software (ADMS) was used to analyse 2678 studies of children from birth to 5 years of age, obtaining local diagnostic reference levels (DRLs) in terms of entrance surface air kerma. Given local DRL for infants and chest exams exceeded the European Commission (EC) DRL, an optimisation was performed decreasing the kVp and applying the automatic control exposure...

BACKGROUND: Misinterpretation of medical images is an important source of diagnostic error. Errors can occur in different phases of the diagnostic process. Insight in the error types made by learners is crucial for training and giving effective feedback. Most diagnostic skill tests however penalize diagnostic mistakes without an eye for the diagnostic process and the type of error. A radiology test with stepwise reasoning questions was used to distinguish error types in the visual diagnostic process...

BACKGROUND: Molecular testing in advanced lung cancer is standard in guiding treatment selection. However, population-wide implementation of testing remains a challenge. We developed a knowledge translation intervention to improve understanding among diagnostic specialists about molecular testing and appropriate diagnostic sampling in lung cancer. METHODS: Specialty-specific education programs were developed from existing literature and input from Canadian leaders in lung pathology, respirology, interventional radiology, thoracic surgery, radiation and medical oncology...

BACKGROUND: Dyssegmental dysplasia Silverman-Handmaker (DDSH; MIM 224410) type is an extremely rare skeletal dysplasia caused by functional null mutations in the perlecan gene. Less than forty cases are reported in the literature, of which only four were prenatally detected. METHODS: We report on a dizygotic twin pregnancy from consanguineous parents for which one of the twins presented prenatally with severe micromelia, limb bowing and scoliosis, and postnatally with clinical and radiological features compatible with a diagnosis of dyssegmental dysplasia...

A previously known association of tuberculosis (TB), now a global emergency, with diabetes mellitus (DM), a chronic disease of increasing prevalence worldwide, has resurfaced. DM is a recognised TB risk factor and M. tuberculosis infection usually disturbs glycoregulation. We aimed to estimate DM prevalence among TB patients and to analyse clinical and radiologic manifestations of TB in this group. The cross-sectional study included 1017 patients discharged with a TB diagnosis from a tertiary level facility in a five-year period...

A 3-month-old intact male Prague ratter was presented to the emergency service for evaluation of progressive lethargy, weakness, coughing and labour breathing after an episode of resistance to oral deworming. The patient exhibited depression, increased respiratory effort and cyanosis at initial presentation. Results of first diagnostic work-up (complete blood cell count, biochemistry panel and thoracic x-rays) were all consistent with aspiration pneumonia. The puppy was initially treated with balanced isotonic crystalloids, broad spectrum antibiotics, nebulization with thoracic coupage and was transferred to an infant incubator with a sustained FiO2 of 40-50%...

Importance: Patients with somatic overgrowth commonly require surgical intervention to preserve function and improve cosmesis. To our knowledge no observation of scarring outcomes in this population has been published to date. Objective: To observe the frequency of abnormal scarring in patients with somatic overgrowth and sequencing-verified mutations in the PIK3CA gene. Design, Setting, and Participants: This retrospective study evaluated scarring outcomes in patients with PIK3CA-related overgrowth...

BACKGROUND: Thoracic spine cancer metastases is frequently the cause of neurological deficits. Despite the availability of diagnostics, delays in treatment are still quite common. The aim of this work is to analyze the reasons for delayed diagnostics and treatment, in patients with neurological deficits in the course of metastatic spine disease. METHODS: In our study patients medical data was analyzed from 2013 to 2015. The analysis covered the following aspects: symptoms of metastases, time of neurological deficits occurrence, where and when initial diagnostics were performed, time from diagnosis to proper surgical treatment in an oncological centre...

OBJECTIVES: To describe facial sinus anatomy from an endoscopic perspective and present a radiologic classification. METHODS: Facial sinus was studied by endoscopy and high-resolution computed tomography (HRCT) scan in 39 temporal bones that underwent exclusive transcanal endoscopic approach. A radiomorphologic classification based on the relationship between the facial sinus and the mastoid portion of the facial nerve is created as follows. In type A facial sinus, the pneumatization of the facial sinus did not extend medially or posteriorly to the mastoid portion of the facial nerve...

Isolated fractures of the orbital floor or medial wall are often referred to as blowout fractures (BOFs). Debilitating double vision and aesthetic deformity may affect the patients' quality of life and daily living skills, for instance, working or driving a car. The management of blowout fractures is, however, challenging, since not all fractures demand surgery. Some patients may have symptoms which subside, or may never develop symptoms. Due to a lack of evidence, there are still considerable differences in opinion on the criteria for surgery...

BACKGROUND: Whilst laparoscopic repair is the most common surgical procedure for the treatment of large hiatal hernias, knowledge of long-term outcomes (>10 years) is scarce. The aim of this study was to evaluate the long-term results following this approach, in particular the hernia recurrence rate and the impact of repair on quality of life (QoL). METHODS: Patients were identified from a prospective database. A standardized questionnaire was used to assess symptoms and a barium swallow radiograph was performed to determine anatomy...

Recent advances in highly conformal radiotherapies greatly extend the indications for radiotherapy of liver tumors. However, because of poor tolerance to hepatic radiation, estimation of the intensity of irradiation of the liver is important, particularly for a cirrhotic liver. Knowledge of radiation-induced hepatitis is important for understanding how to optimize hepatic radiation therapy. Pathological changes of the irradiated liver, which include perivenular fibrosis, sinusoidal obstruction, and damage to Kupffer cells and hepatocytes, can be visualized using clinical imaging techniques...

We present the case of a retrobulbar abscess that developed secondary to the repair of an oroantral communication. Orbital abscesses have been described in relation to odontogenic infections, facial injury, sinusitis, and after dental extractions but, to the best of our knowledge, none has been reported in these circumstances. Retrobulbar abscess is a rare complication, but early clinical and radiological diagnosis, and urgent decompression are vital because it comes with considerable risk of irreversible visual impairment...

RATIONALE: Small bowel adenocarcinoma (SBA) is an uncommon gastrointestinal cancer, thus limited data about treatment for advanced disease are available. The lack of specific guidelines has justified the use of therapeutic protocols usually applied in advanced colorectal cancer. Few and preliminary data have suggested possible clinical benefit from the use of target therapy such as bevacizumab and cetuximab. PATIENT CONCERNS: We present the case of a young woman who was admitted to the emergency department for acute abdominal pain, nausea, and vomiting related to a jejunal stenosis...
