PURPOSE: The purpose of this article was to determine whether a novel finding on coronal computed tomography (CT) can help differentiate usual interstitial pneumonia (UIP) from nonspecific interstitial pneumonia (NSIP) in order to obviate lung biopsy. MATERIALS AND METHODS: Two chest radiologists, blinded to clinical data, reviewed 3 preselected coronal images from CT scans, performed within 1 year of surgical lung biopsy (SLB), from 51 patients with biopsy-proven UIP and 15 with biopsy-proven NSIP...

Introduction: Congenital cystic adenomatoid malformation (CCAM) is a rare anomaly. The mechanisms and the time at which the abnormality develops are still unclear. The malformation is characterized by the presence of single large or multiple but smaller cysts. Aim: To present the experience of our medical centre, the Polish Mother's Memorial Hospital - Research Institute. Material and methods: We analysed the medical records of 32 neonates hospitalized in 2008-2017 at the Department of Paediatric Surgery and Urology ICZMP due to pre- or postnatally diagnosed congenital cystic adenomatoid malformation...

We aimed to develop a computerized method for the detection of radiopaque markers, such as R and L in chest and abdomen radiography by using the generalized Hough transform and the template matching. To develop the computerized method, we used 200 chest and abdomen images in our institution as training cases. First, two template images for R and L markers were created with the same exposure condition as a chest X-ray. Following various image processing, such as edge detection, thinning and Hough transformed, a look-up table that consisted of distance and direction pairs was built for the generalized Hough transform...

Extravascular lung water (index) (EVLW(I)) can be estimated using transpulmonary thermodilution (TPTD). Computed tomography (CT) with quantitative analysis of lung tissue density has been proposed to quantify pulmonary edema. We compared variables of pulmonary fluid status assessed using quantitative CT and TPTD in critically ill patients. In 21 intensive care unit patients, we performed TPTD measurements directly before and after chest CT. Based on the density data of segmented CT images we calculated the tissue volume (TV), tissue volume index (TVI), and the mean weighted index of voxel aqueous density (VMWaq)...

The use of transthoracic ultrasound has acquired a wide consensus among respiratory physicians during the last few years. The developing of portable and easily available devices favorites patient's bedside evaluation. Transthoracic ultrasound provides rapid, real-time and low-cost diagnostic information, allowing image-guided chest interventions and reducing procedural risks. The different acoustic impedance between aerated and not aerated organs produces artifacts known as A lines, B lines, sliding sign, lung point, etc...

BACKGROUND: Preoperative evaluation and awareness of anatomical variations in the pulmonary vessel is essential for a secure pulmonary resection. We herein present a patient who underwent complex pulmonary resection for lung cancer with a mediastinal lingular and basal pulmonary artery that had been detected by preoperative three-dimensional computed tomography. CASE PRESENTATION: The patient was an asymptomatic 66-year-old woman who had a 39-pack-year smoking habit...

Background: Despite that confirmative diagnosis of pulmonary drug-sensitive tuberculosis (DS-TB) and multidrug resistant tuberculosis (MDR-TB) is determined by microbiological testing, early suspicions of MDR-TB by chest imaging are highly desirable in order to guide diagnostic process. We aim to perform an analysis of currently available literatures on radiological signs associated with pulmonary MDR-TB. Methods: A literature search was performed using PubMed on January 29, 2018...

Anterior chest wall (ACW) inflammation is not an uncommon finding in patients with axial spondyloarthritis (ax-SpA) and reportedly occurs in 26% of these patients. Radiologists may only be familiar with spinal and peripheral joint imaging, possibly due to the inherent challenges of ACW imaging on some cross-sectional imaging modalities. Knowledge of relevant joint anatomy and the location of sites of inflammation allows the interpreting radiologist to better plan appropriate imaging tests and imaging planes...

BACKGROUND: In women with low to intermediate risk of coronary artery disease (CAD), prognostic detection strategies have been controversial. We present the follow-up data of the SMART trial in peri/postmenopausal women at low to intermediate risk of CAD. OBJECTIVES: To determine the value of contrast stress echocardiography (CSE), stress electrocardiogram (sECG), and serum biomarkers for prediction of cardiovascular events (CE) in peri/postmenopausal women at low to intermediate risk of CAD...

Testicular cancer is the most common solid tumor among males 15 to 34 years of age, with an estimated 8,850 new cases and 410 deaths during 2017 in the United States. With effective treatment, the overall five-year survival rate is 97%. Risk factors for testicular cancer include undescended testis (cryptorchidism), personal or family history of testicular cancer, age, ethnicity, and infertility. The U.S. Preventive Services Task Force recommends against routine screening in asymptomatic men. Men with symptoms should receive a complete history and physical examination...

Background: Intracoronary (IC) injection of mesenchymal stem cells (MSCs) results in a prompt decrease of absolute myocardial blood flow (AMF) with late and incomplete recovery of myocardial tissue perfusion. Here, we investigated the effect of decreased AMF on oxidative stress marker matrix metalloproteinase-2 (MMP-2) and its influence on the fate and homing and paracrine character of MSCs after IC or intramyocardial cell delivery in a closed-chest reperfused myocardial infarction (MI) model in pigs...

Introduction: Surgery for cardiac trauma is considered fatal and for wounds of the colon by associated sepsis is normally considered; however, conservative management of many traumatic lesions of different injured organs has progressed over the years. Presentation of the Case: A 65-year-old male patient presented with multiple shotgun wounds on the left upper limb, thorax, and abdomen. On evaluation, he was hemodynamically stable with normal sinus rhythm and normal blood pressure, no dyspnea, or abdominal pain...

RATIONALE: Subarachnoid hemorrhage (SAH) is a common and serious disease and one of the most important differential diagnoses in the emergency department. PATIENT CONCERNS: A 39-year-old female patient with a 12 years' history of migraine, presented with a sudden headache combined with motor aphasia. Physical examination suggested probable positive neck resistance. SAH was confirmed by magnetic resonance imaging. In addition, spinal digital subtraction angiography and spinal vascular computed tomography angiography indicated spinal arteriovenous malformation (SAVM)...

RATIONALE: Penetrating neck trauma has a mortality of 3% to 6% and is associated with serious complications, mainly due to the high density of vital structures in this area and the lack of corresponding protection from bone. PATIENT CONCERNS: A 55-year-old man who suffered neck trauma involving the parotid gland, caused by a rebar, after suffering a fall from the second floor of a building. DIAGNOSES: Penetrating neck trauma. INTERVENTIONS: The patient underwent a neck exploration under general anesthesia in the emergency operating room and tracheotomy was performed prophylactically...

BACKGROUND AND OBJECTIVE: This study aimed to establish a system that can classify severe asthma on the basis of airway remodeling patterns visualized by computed tomography (CT) images and to evaluate the clinical characteristics of individual image-based subtypes. METHODS: Chest CT images of severe asthma patients were retrospectively evaluated to classify phenotypes by site of airway involvement and remodeling.

PURPOSE: To report a case of Purtscher retinopathy imaged with optical coherence tomography angiography. METHODS: Case-report. Left eye fundoscopic examination in a 21-year old male after a road traffic accident with chest compression revealed multiple peri-papillary cotton-wool spots and intra- and pre-retinal hemorrhages. A diagnosis of Purtscher retinopathy was assumed. RESULTS: In both the superficial and deep retinal plexuses, acute stage optical coherence tomography angiography identified multiple irregular areas of capillary non-perfusion that extended beyond the clinically visible peri-papillary cotton-wool spots...
