The accuracy and precision of plain CT chest for diagnosis of anaemia.

Objective: To determine the accuracy and precision of anaemia diagnosis with plain computed tomography of chest by keeping complete blood count as the gold standard.

Methods: The cohort study was conducted from January 1 to December 31, 2020, at Dow University of Health Sciences, Karachi, and comprised patients attending the hospital regardless of gender or age. The subjects underwent complete blood count and high-resolution computed tomography scan of chest with 7-day interval.

Benign and malignant breast diseases during pregnancy and lactation: a diagnostic challenge.

Objective: To determine the frequency of breast cancer associated with pregnancy and lactation, and to evaluate the lesions on ultrasound.

Methods: The descriptive, observational study was conducted at the Dow Institute of Radiology, DUHS, Karachi from December 2020 to August 2021, and comprised of pregnant and lactating women with clinically palpable breast lumps and/or painful breast. The margins, orientation, echo pattern and associated features of the lesions were studied on ultrasound and were assigned a Breast Imaging Reporting and Data System grade.

Inter observer reliability for peritoneal carcinomatosis at computed tomography.

Objective: To determine whether there is inter-observer reliability between radiologists for reporting peritoneal carcinomatosis and computed tomography peritoneal carcinomatosis index estimation.

Methods: The retrospective, cross-sectional study was conducted at Dow Institute of Radiology, Dow University of Health Sciences (DUHS), Ojha campus and comprised computed tomography scans done between December 1, 2019, to May 31, 2020, that were extracted from the institutional database searched using key words 'peritoneal carcinomatosis' and/or 'serosal deposits'. The first readers had 1-4 years of post-fellowship experience, while the 2nd readers were senior radiologists.

The Asymptomatic Dissecting Aortic Aneurysm: An Incidental Finding on CT.

We report a case of 65-year male patient, a known hypertensive and a chronic smoker, who presented to the Civil Hospital, Karachi with complaints of cough, hemoptysis and shortness of breath for three weeks. The chest radiograph showed left apical solitary pulmonary nodule (SPN) and aneurysmal dilatation of the descending thoracic aorta. He was further investigated with contrast enhanced computed tomography (CECT) scan of chest, which apart from demonstrating malignant pulmonary lesion, surprisingly revealed Stanford type B descending thoracic aortic dissecting aneurysm with intramural hematoma, jeopardising renal and splanchnic circulation.

Gastroduodenal Artery Pseudoaneurysm and Aberrant Right Hepatic Artery.

We present a case of 36-year male patient who was referred to the Civil Hospital, Karachi with intermittent abdominal pain and vomiting for the last 2 years. The contrast enhanced CTexamination revealed changes of acute pancreatitis, CTSI 4/10, pancreatic calcifications along with 22x17 mm partially thrombosed pseudoaneurysm of gastroduodenal artery. The aberrant right hepatic artery was incidentally seen, on the arterial phase acquisition, arising directly from abdominal aorta.
