Background: Endoscopic methods (gastroscopy and colonoscopy) are considered fundamental for the diagnosis of gastrointestinal bleeding. In recent years, multidetector computed tomography (MDCT) has also gained importance in diagnosing gastrointestinal bleeding, particularly in hemodynamically unstable patients and in cases with suspected lower gastrointestinal tract bleeding. CT can detect both the source and the cause of active gastrointestinal bleeding, thereby expediting treatment initiation...

Chordomas are rare tumors that can develop anywhere along the craniospinal axis. These tumors present challenges with respect to diagnosis and treatment due to a high rate of recurrence, even after multiple surgeries, and the propensity to involve any region within the craniospinal axis. New developments in radiation therapy have improved recurrence-free survival in patients with chordomas. Different regimens of chemotherapy and molecularly-targeted therapies, as adjuvants to surgery, have been described in individual case reports and case series...

Background: Radiation exposure due to computed tomography (CT) has become an important issue, as the number of CT examinations has been increasing worldwide. Radiation doses associated with CT are higher in comparison to other imaging procedures. CT-related radiation doses should be monitored and controlled in order to ensure reduction of radiation exposure and optimization of image quality. The aim of this study was to evaluate radiation doses in adult patient who underwent routine CT brain examinations, and to assess how CT scanning protocols affect patient doses in practice...

Background: Acute gastrointestinal bleeding is an emergency with a high morbidity and mortality. Early diagnosis and appropriate intervention can be lifesaving and can prevent long-term complications. Case Report: In this case report, we discuss and illustrate the role of CT angiography in the evaluation of acute, active gastrointestinal haemorrhage and show its usefulness prior to embolization. We describe a 15-year-old girl with granulomatosis with polyangiitis, formerly known as Wegener's granulomatosis...

Background: In accordance with the European guidelines on rhinosinusitis and nasal polyps (EPOS 2012), CT is used as the main imaging modality for the assessment intensity of inflammatory lesions.The aim of this study was to measure the differences in the assessment of inflammatory changes in the paranasal sinuses due to different parameters of width (W) and length (L) of the CT window. Material/Methods: A retrospective analysis included 44 CT scans of the paranasal sinuses that were performed in adults...

Background: Xerostomia is one of the commonest radiation-induced complications in patients with head and neck carcinoma. The aim of this study was to assess structural variations in parotid glands induced by radiation therapy in patients with oral carcinoma with contras-enhanced computed tomography (CECT). Material/Methods: A retrospective study was performed in 41 patients with oral carcinoma who underwent CECT for head and neck malignancies before and after radiotherapy...

Background: To assess the role of diffusion-weighted MR imaging in differentiation between Graves' disease and painless thyroiditis. Material/Methods: A prospective study was conducted among 37 consecutive patients with untreated thyrotoxicosis (25 female and 12 male; mean age of 44 years) and 15 ageand sex-matched controls. Diffusion-weighted MR imaging of the thyroid gland was performed in patients and controls. The apparent diffusion coefficient (ADC) value of the thyroid gland was calculated and correlated with Tc-99m uptake and thyroid function tests of the patients...

Background: Restricted diffusion that is found on magnetic resonance diffusion-weighted imaging (DWI) typically indicates acute ischaemic stroke. However, restricted diffusion can also occur in other diseases, like metastatic brain tumours, which we describe in this case report. Case Report: A 57-year-old male, with a diagnosis of small-cell cancer of the right lung (microcellular anaplastic carcinoma), was admitted with focal neurological symptoms. Initial brain MRI revealed multiple, disseminated lesions that were hyperintense on T2-weighted images and did not enhance after contrast administration; notably, some lesions manifested restricted diffusion on DWI images...

Background: Testicular adrenal rest tumours (TARTs) are benign testicular masses that are found in inadequately treated patients with congenital adrenal hyperplasia (CAH). Recognizing this association and identifying characteristic ultrasound features of TARTs is important so as to avoid misdiagnosing them as malignancies, which can lead to unnecessary interventions. Case Report: We describe a case of a 9-year-old boy, with a diagnosis of CAH and precocious puberty, who was referred to our department for an ultrasound evaluation of the abdomen and scrotum...

Fistula-in-ano, or perianal fistula, is a challenging clinical condition for both diagnosis and treatment. Imaging modalities such as fistulography, anal endosonography, perineal sonography, magnetic resonance imaging (MRI), and computed tomography (CT) are available for its evaluation. MRI is considered as the modality of choice for an accurate delineation of the tract in relation to the sphincter complex and for the detection of associated complications. However, its availability and affordability is always an issue...

Background: With increasingly aging populations, chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death today. Emphysematous changes, an important component of the disease, must be determined on HRCT, either qualitatively or quantitatively. The purpose of this study was to evaluate features that help determine emphysematous changes and correlate them with respiratory function tests (RFTs). Material/Methods: A total of thirty COPD patients and a control group of the same size, matched for age, were included in the study...

Background: Kidney tumors account for about 3% of tumors in adults. The primary therapy of renal cancer is the surgical removal. Traditionally, and also modern procedures are performed to remove the kidneys, especially when the tumor involves the entire kidney. In the cases of unresectable tumors embolization is used as a palliative procedure. Case Report: The aim of this study is to present the case of endovascular treatment of renal cell carcinoma in patient with solitary kidney...

Fahr syndrome is a rare neurodegenerative disorder characterized by symmetrical, bilateral calcifications in the basal ganglia, nucleus gyrus and cerebral cortex. The continuous advancement as well as widespread use of brain imaging have contributed to the increasing detection rates of such changes. Nevertheless, their etiology is understood only partially and the methods of causative treatment are limited. Due to various symptoms, Fahr syndrome may resemble diseases from the field of neurology, psychiatry, cardiology and even urology...

Chronic suppurative otitis media (CSOM) refers to the middle ear inflammation which is clinically characterized by the discharging ear, hearing deficit, fever and otalgia. Although a clinical diagnosis, imaging is imperative to rule out associated complications which apart from causing hearing deficit, may prove fatal at times. Both high resolution computed tomography (HRCT) and MRI are helpful in evaluating middle ear pathologies, usage being indication specific. Due to its excellent spatial resolution, HRCT is invaluable in assessment of chronically discharging ears, especially to look for bone erosion and the integrity of the ossicles...
