T1 signal intensity ratio of the pancreas as an imaging biomarker for the staging of chronic pancreatitis.

Purpose: Our purpose was to validate the T1 SIR (T1 score) as an imaging biomarker for the staging of CP in a large, multi-institutional, prospective study.

Methods: The prospective study population included 820 participants enrolled in the PROCEED study from nine clinical centers between June 2017 and December 2021. A radiologist at each institution used a standardized method to measure the T1 signal intensity of the pancreas and the reference organs (spleen, paraspinal muscle, liver), which was used to derive respective T1 scores.

Lactoferrin amyloid presenting as a mural nodule in a pancreatic cystic lesion prompting pancreatoduodenectomy: a case report.

Background: Amyloid deposition in pancreas is rare. Lactoferrin amyloid deposition has not been reported in pancreas, till date. Presence of enhancing mural nodule in a cyst on imaging is a worrisome feature for malignancy, and warrants surgical resection in a surgically fit candidate, as per Fukuoka guidelines for management of cystic lesions in pancreas.

Inter-observer variability of radiologists for Cambridge classification of chronic pancreatitis using CT and MRCP: results from a large multi-center study.

Purpose: Determine inter-observer variability among radiologists in assigning Cambridge Classification (CC) of chronic pancreatitis (CP) based on magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP) and contrast-enhanced CT (CECT).

Methods: Among 422 eligible subjects enrolled into the PROCEED study between 6/2017 and 8/2018, 39 were selected randomly for this study (chronic abdominal pain (n = 8; CC of 0), suspected CP (n = 22; CC of 0, 1 or 2) or definite CP (n = 9; CC of 3 or 4). Each imaging was scored by the local radiologist (LRs) and three of five central radiologists (CRs) at other consortium sites.

Pancreatic Incidentalomas: A Management Algorithm for Identifying Ectopic Spleens.

Background: Identification of incidental pancreatic lesions is increasing because of advancements in imaging. Diagnosis remains a challenge for clinicians, with intrapancreatic accessory spleens (IPAS) posing a unique dilemma. IPAS are frequently resected because of inability to exclude alternate diagnoses, subjecting patients to unnecessary risk.

Pancreatic endometrial cyst mimics mucinous cystic neoplasm of the pancreas.

Pancreatic cysts include a variety of benign, premalignant, and malignant lesions. Endometrial cysts in the pancreas are exceedingly rare lesions that are difficult to diagnose pre-operatively. This report describes the findings in a 43-year-old patient with a recent episode of acute pancreatitis who presented with a large cyst in the tail of the pancreas.

Laparoscopic sleeve gastrectomy: a guide to postoperative anatomy and complications.

The purpose of this pictorial essay is to review the surgical technique, postoperative anatomy, and potential complications of the laparoscopic sleeve gastrectomy. As the laparoscopic sleeve gastrectomy becomes an increasingly popular bariatric surgery, it is important for radiologists to familiarize themselves with the procedure and possible complications.
