Objectives: To determine the diagnostic accuracy of colour Doppler of cerebral and umbilical pulsatality in diagnosing IUGR, taking birth weight as gold standard. Study Design: Descriptive, Cross Sectional Study. Setting: Department of Radiology, DHQ Hospital, Faisalabad. Period: 30th May 2016 to 29th November 2016. Material & Methods: Total 129 clinically suspected IUGR, 18 to 40 years of age with singleton pregnancy were included. Patients having Hb< 8.5 g/dl, chromosomal abnormality, chronic infections, severe systemic illness like uncontrolled diabetes mellitus, cardiac disease, renal or hepatic disease were excluded. Colour Doppler Ultrasonography of the cerebral and umbilical artery was performed in every patient and looked for IUGR. Colour Doppler sonography findings were compared with birth weight of baby. Results: Mean age was 30.26 ± 4.67 years. The mean gestational age was 38.60 ± 1.27 weeks. Mean parity was 2.68 ± 0.74. In Colour Doppler Ultrasonography positive patients, 64 were true positive while 09 were false positive. Among, 56 Colour Doppler Ultrasonography negative patients, 07 were false negative while 49 were true negative. Overall sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of colour Doppler of cerebral and umbilical pulsatality in diagnosing IUGR, taking birth weight as gold standard was 90.14%, 84.49%, 87.67%, 87.50% and 87.60% respectively. Conclusion: This study concluded that diagnostic accuracy of colour Doppler of cerebral and umbilical pulsatality in diagnosing IUGR is quite high.

Arterial Branch

Calibre-persistent labial artery (CPLA) is a commonly underdiagnosed vascular lesion of the lip. CPLA is an arterial branch that penetrates the submucosal tissue without loss of calibre. Clinical diagnosis is significant as misdiagnosis can lead to profuse haemorrhage following an excisional biopsy or surgical excision. Colour Doppler ultrasonography is a safe and non-invasive diagnostic tool to confirm the diagnosis. Here, we report a case of a 24-year-old man who complained of an asymptomatic pulsating non-progressive nodule on the left side of upper lip initially diagnosed as peripheral angiomatous lesion. Diagnosis was confirmed by high-resolution Colour Doppler Ultrasonography. The purpose of this case report is to highlight the clinical importance and diagnosis of a rarely reported soft tissue swelling of the lip to the attention of clinicians.
