Role Of Multi-Parametric (Mp) Mri In Prostate Cancer, Syed Muhammad Nazim, Ather Enam, Basit Salam Aug 2018

Role Of Multi-Parametric (Mp) Mri In Prostate Cancer, Syed Muhammad Nazim, Ather Enam, Basit Salam

Section of Urology

Multi-parametric magnetic resonance imaging is increasingly being recommended as standard imaging modality for prostate cancer diagnosis and staging. It comprises structural T2 and T1 sequences supplemented by functional imaging techniques, i.e. diffusion-weighted, dynamic contrast enhanced and spectroscopic imaging. Pre-biopsy multi-parametric magnetic resonance imaging is recommended for both detection and staging as it avoids biopsy artefact, and when normal, has a negative predictive value of 95% for significant cancer. Magnetic resonance imaging-guided prostate biopsy targets only area(s) considered to be suspicious for prostate cancer, hence resulting in improved accuracy. Dynamic contrast enhancing helps in the detection of cancer and for the …

Twin Reversed Arterial Perfusion Sequence: Assessing The Role Of The Correct Imaging Modality In A Rare Clinical Entity, Imrana Masroor, Sarah Saleem, Aliya Aziz, Romana Idress Jul 2018

Twin Reversed Arterial Perfusion Sequence: Assessing The Role Of The Correct Imaging Modality In A Rare Clinical Entity, Imrana Masroor, Sarah Saleem, Aliya Aziz, Romana Idress

Department of Radiology

Acardiac twin formation is a rare anomaly. It is one of the most extreme complications of monozygotic twin pregnancies. Such occurrences are brought about when a normal twin donates blood to an abnormal twin through its umbilical arteries via vascular anastomoses at the level of the placenta, which is termed as twin reversed arterial perfusion sequence (TRAPS). Twin reversed arterial perfusion sequence is considered a rare variant of twin-to-twin transfusion syndrome. Due to the considerable blood transfer from the healthy twin to the parasitic one, cardiac failure can ensue in the healthy twin. The mortality of the acardiac twin is …

Unicameral Bone Cysts: Current Concepts, Shahryar Noordin, Salim Allana, Masood Umer, Mujahid Jamil, Kiran Hilal, Nasir Ud Din

Section of Orthopaedic Surgery

Unicameral bone cysts (UBC) or simple/solitary bone cysts are benign fluid filled cavities that enlarge over time, resulting in thinning of the bone. Usually these cysts are reported in the metaphyseal areas of long bones with open physes. 85% of UBCs occur almost exclusively in children and adolescents. UBCs are more aggressive in the first decade of life and correspondingly the recurrence rate for these patients is four times that for adolescents. The proximal humerus and femur account for almost 90% of these cases. UBCs are classified as active when they are within 1 cm of the physis and latent …
