Chest and Abdominal Radiograph 101
Chest and Abdominal Radiograph 101 Ketsia Pierre MD, MSCI July 16, 2010 Objectives • Chest radiograph – Approach to interpreting chest films – Lines/tubes – Pneumothorax/pneumomediastinum/pneumopericar dium – Pleural effusion – Pulmonary edema • Abdominal radiograph – Tubes – Bowel gas pattern • Ileus • Bowel obstruction – Pneumoperitoneum First things first • Turn off stray lights, optimize room lighting • Patient Data – Correct patient – Patient history – Look at old films • Routine Technique: AP/PA, exposure, rotation, supine or erect Approach to Reading a Chest Film • Identify tubes and lines • Airway: trachea midline or deviated, caliber change, bronchial cut off • Cardiac silhouette: Normal/enlarged • Mediastinum • Lungs: volumes, abnormal opacity or lucency • Pulmonary vessels • Hila: masses, lymphadenopathy • Pleura: effusion, thickening, calcification • Bones/soft tissues (four corners) Anatomy of a PA Chest Film TUBES Endotracheal Tubes Ideal location for ETT Is 5 +/‐ 2 cm from carina ‐Normal ETT excursion with flexion and extension of neck 2 cm. ETT at carina Right mainstem Intubation ‐Right mainstem intubation with left basilar atelectasis. ETT too high Other tubes to consider DHT down right mainstem DHT down left mainstem NGT with tip at GE junction CENTRAL LINES Central Venous Line Ideal location for tip of central venous line is within superior vena cava. ‐ Risk of thrombosis decreased in central veins. ‐ Catheter position within atrium increases risk of perforation Acceptable central line positions • Zone A –distal SVC/superior atriocaval junction. • Zone B – proximal SVC • Zone C –left brachiocephalic vein. Right subclavian central venous catheter directed cephalad into IJ Where is this tip? Hemiazygous Or this one? Right vertebral artery Pulmonary Arterial Catheter Ideal location for tip of PA catheter within mediastinal shadow. -

Deep Sulcus Sign Developed in Patient with Multiple Fibrous Bands Between the Parietal and Visceral Pleura
eISSN: 2508-8033 Brief Image in Trauma pISSN: 2508-5298 Deep Sulcus Sign Developed in Patient with Multiple Fibrous Bands between the Parietal and Visceral Pleura Chan Yong Park1, Kwang Hee Yeo1, Sung Jin Park1, Ho Hyun Kim1, Chan Kyu Lee1, Seon Hee Kim1, Hyun Min Cho1, Seok Ran Yeom2 1Department of Trauma Surgery, Pusan National University Hospital, Busan, Korea 2Department of Emergency Medicine, Pusan National University Hospital, Busan, Korea A deepening of the costophrenic angle occurs in cases with a deep sulcus sign. We report a case of deep sulcus sign in a 47-year-old man who fell from the fifth floor. Supine chest radiography showed a right-sided pneumothorax with deep sulcus sign. Chest computed tomography (CT) demonstrated a large pneumothorax with multiple fibrous bands between the parietal and visceral pleura of the upper lobe of the right lung. (Trauma Image Proced 2017(1):7-9) Key Words: Pneumothorax; X-Rays; Diagnosis; Tomography, X-Ray computed CASE A 47-year-old man presented to the emergency department after falling from a fifth floor height. His vital signs were systolic blood pressure 60 mmHg, pulse rate 111 beats/min, respiration rate 31 breaths/min, body temperature, 36.4℃, and oxygen saturation 96%. The injury severity score was 29, revised trauma score 5.15, trauma and injury severity score 74.8%. His arterial blood gas analysis was pH 7.35, pCO2 29 mmHg, pO2 75 mmHg, hemoglobin 16.7, SaO2 94%, lactic acid 11.8 mmol/L, and base excess -8.0.

CT Signs in the Lungs Girish S
CT Signs in the Lungs Girish S. Shroff, MD,* Edith M. Marom, MD,† Myrna C.B. Godoy, MD, PhD,* Mylene T. Truong, MD,* and Caroline Chiles, MDz Radiologic signs are often based on items or patterns that are encountered in everyday life. They are especially useful because their observation allows the differential diagnosis to be narrowed, and in some cases, enables a diagnosis to be made. In this review, several clas- sic and newer computed tomography signs in the lungs are discussed. Semin Ultrasound CT MRI 40:265-274 © 2018 Elsevier Inc. All rights reserved.
