Massive subchorionic thrombosis followed by magnetic resonance imaging.

Massive subchorionic thrombosis is a rare condition, defined as a large thrombus confined to the subchorionic space. It is associated with poor perinatal prognosis. However, prenatal diagnosis by ultrasonography is often difficult.

Diffusion-weighted magnetic resonance imaging for detecting lymph node metastasis of rectal cancer.

Background: Preoperative diagnosis of lymph node metastasis is important in determining the optimal therapy for rectal cancer. It has been shown that diffusion-weighted magnetic resonance imaging (DWI) is a useful tool for detecting malignant tumors.

Methods: One hundred twenty-nine consecutive patients with rectal cancer were examined with DWI + conventional (T1-weighted and T2-weighted) MRI and computed tomography (CT).

Intra-arterial infusion chemotherapy with 5-fluorouracil and cisplatin in advanced pancreatic cancer: a feasibility study.

Objective: Our aim was to examine the efficacy and tolerability of intra-arterial infusion chemotherapy with 5-fluorouracil (5-FU) and cisplatin in advanced pancreatic cancer.

Methods: Sixteen patients with unresectable locally advanced or metastatic pancreatic cancer (12 Stage IVa and 4 Stage IVb with liver metastasis) were enrolled. The catheter for intra-arterial infusion was placed at the position to distribute chemotherapeutic drugs to both the pancreatic tumor and the liver.
